⚡ Quick Answer
Aluminum strip is narrow slit coil — typically 6–600 mm wide, 0.1–6.0 mm thick — supplied wound, not flat. Choose 1050/1060/1070 for transformer and capacitor windings where conductivity matters, 3003/3004 for fin stock, channels and general roll forming, 5052 for strength and marine exposure, 6061 for heat-treatable structural strip. The spec that separates suppliers is width tolerance, edge quality (burr) and camber — that is what decides whether your roll former or winding machine runs at speed. See our strip range →
Key Takeaways
- Strip is defined by width, not alloy. It is slit coil, usually 6–600 mm wide; wider is coil, narrower and lighter than ~0.1 mm is usually bought as foil.
- Three quality metrics decide strip price premium: width tolerance (±0.05 mm precision vs ±0.5 mm commodity), edge burr (≤5–10% of thickness), and camber (≤1 mm/m).
- Conductor strip wants purity: 1050/1060/1070 at ≥ 61% IACS for transformer windings, busbar wrap and capacitor rings — every 0.1% Fe costs conductivity.
- Structural strip wants Mg or Mg-Si: 5052 for marine and transport; 6061-T6 when heat-treated strength is required after forming.
- Weight math: kg/m = width(mm) × thickness(mm) × 2.71 ÷ 1000. A 100 × 1.0 mm strip runs 0.271 kg/m — one tonne is ≈ 3,690 m.
- Agree tolerance class and edge condition in writing before ordering — edges cannot be fixed after the strip leaves the slitter.
1. What Is Aluminum Strip? Where the Boundaries Sit
Aluminum strip is flat-rolled aluminum supplied as a narrow wound coil. The industry works with three width/height boundaries — learn them once and every supplier quote becomes comparable:
- Coil → strip: slit below roughly 600 mm width, the product is sold as strip. Master coil widths up to 2,650 mm are covered in the aluminum coil guide.
- Strip → foil: below ~0.1–0.2 mm thickness (and especially in very narrow widths), converters order foil instead — see the aluminum foil guide for the barrier-packaging end of the range.
- Strip → sheet: the same gauge cut into flat rectangles is sheet — the aluminum sheet hub covers cut lengths and plates.
In practice you buy strip when the process is continuous: transformer winding machines, tube mills, roll formers, cable armouring lines, shutter-slat lines, heat-exchanger fin stamping. The coil pays for itself in uptime — no butt-welding sheet offcuts every few metres.
2. How Strip Is Made: Casting, Rolling, Slitting, Levelling
Strip quality is inherited from the coil it is slit from — then refined by the slitting and levelling lines. The two coil routes (covered in depth in the coil guide) are DC-cast + hot/cold rolling (best surface, all alloys) and continuous casting (cheaper, 1xxx/3xxx/8xxx). What slitting adds:
| Step | What Happens | Spec It Sets |
|---|---|---|
| Master coil selection | Pick alloy/temper/gauge from stock or rolling schedule | Alloy, temper, base gauge |
| Circular slitting | Rotary knives cut multiple strips per pass | Width tolerance ±0.05–0.5 mm, knife overlap, burr height |
| Edge trimming / binding | Scrap edges wound off; edge condition set | Slit / deburred / rounded / square edge |
| Tension levelling | Rolls stretch the strip slightly for flatness | Camber ≤ 1 mm/m, out-of-flat ≤ 2 mm |
| Annealing (if required) | Furnace cycle to O/H2x temper | Grain size, formability |
| Surface finishing (optional) | Coating, anodising, embossing lines | Coating class, dyne, colour |
| Packing | Eye-to-sky wooden crates, VCI paper | Moisture protection, coil ID traceability |
Why slitting quality dominates complaints: a badly set knife gap leaves a burred or work-hardened edge that cracks in roll forming or frays transformer windings. Knife wear shows up as progressively worsening burr along the coil — good mills regrind on a schedule and record burr height per coil. If your process is edge-sensitive (winding, wiper seals, anodising), specify burr ≤ 10% of thickness and ask for the slitter QC record.
3. Strip vs Coil vs Foil vs Sheet: What to Order
| Attribute | Aluminum Strip | Aluminum Coil (master) | Aluminum Foil | Aluminum Sheet |
|---|---|---|---|---|
| Width | 6–600 mm | 600–2,650 mm | Any (typically 20–1,600 mm) | Cut lengths, any |
| Thickness | 0.1–6.0 mm | 0.15–6.0 mm | 0.0055–0.2 mm | 0.2–6.0 mm (sheet) / >6 mm plate |
| Supply format | Wound, always | Wound, always | Wound or precut sheets | Flat rectangles |
| Typical buyer | Roll formers, winding shops, tube mills | Service centres, coaters | Converters, packaging | Fabricators, machine shops |
| Key spec driver | Width tolerance + edge | Gauge + flatness | Pinholes + barrier | Flatness + surface |
| HXM page | Strip hub | Coil guide | Foil guide | Sheet hub |
Rule of thumb: continuous process + narrow width = strip; continuous process + wide web = coil; barrier packaging = foil; discrete parts = sheet or circles. Cross-shopping the wrong form usually shows up as freight waste (buying master coil you must re-slit) or uptime loss (sheet feeding a roll former).
4. Alloy Selection: 1xxx / 3xxx / 5xxx / 6xxx Strip by Application
| Series | Common Strip Alloys | Character | Best Applications |
|---|---|---|---|
| 1xxx (pure) | 1050, 1060, 1070, 1100 | ≥ 99% Al, highest conductivity & formability, lowest strength | Transformer windings, capacitor rings, busbar wrap, decorative trim, nameplate |
| 3xxx (Al-Mn) | 3003, 3004, 3005, 3105 | ~20% stronger than 1xxx, weldable, weather-safe | Fin stock, HVAC channels, gutters, cladding trims, flexible duct |
| 5xxx (Al-Mg) | 5052, 5083, 5154, 5056 | Highest non-heat-treatable strength, marine-grade corrosion | Cable armour, marine trim, truck body panels, pressure-sensitive uses |
| 6xxx (Al-Mg-Si) | 6061, 6060, 6063 | Heat-treatable to T4/T6, structural | Structural strip, brackets, formed-then-aged profiles |
| 8xxx | 8011 | Foil-grade, high strength in thin gauge | Capsule foil strip, closure liners |
Alloy deep-dives: 1100 guide, 3003 guide, 3004 guide, 5052 sheet guide, 5083 marine guide and 6061-T6 properties. Product pages: 1050 strip, 1060 strip, 1070 strip, 3003 strip, 5052 strip, 5083 strip, 6061 strip — plus the 1060 vs 1050 comparison for picking between near-identical conductor grades.
5. Chemical Composition of Common Strip Alloys (ASTM B209 / EN 573)
| Alloy | Si | Fe | Cu | Mn | Mg | Cr | Zn | Purity / Notes |
|---|---|---|---|---|---|---|---|---|
| 1050 | 0.25 | 0.40 | 0.05 | 0.05 | 0.05 | 0.05 | 0.05 | Al ≥ 99.50% |
| 1060 | 0.25 | 0.35 | 0.05 | 0.03 | 0.03 | 0.05 | 0.05 | Al ≥ 99.60% |
| 1070 | 0.20 | 0.25 | 0.04 | 0.03 | 0.03 | 0.05 | 0.05 | Al ≥ 99.70% |
| 1100 | 0.95 (Si+Fe) | — | 0.05–0.20 | 0.05 | 0.05 | 0.05 | 0.10 | Al ≥ 99.00% |
| 3003 | 0.60 | 0.70 | 0.05–0.20 | 1.00–1.50 | 0.10 | 0.10 | 0.10 | Al balance |
| 3004 | 0.30 | 0.70 | 0.25 | 1.00–1.50 | 0.80–1.30 | 0.10 | 0.25 | Al balance |
| 3105 | 0.60 | 0.70 | 0.30 | 0.30–0.80 | 0.20–0.80 | 0.20 | 0.40 | Al balance |
| 5052 | 0.25 | 0.40 | 0.10 | 0.10 | 2.20–2.80 | 0.15–0.35 | 0.10 | Al balance |
| 5083 | 0.40 | 0.40 | 0.10 | 0.40–1.00 | 4.00–4.90 | 0.05–0.25 | 0.25 | Al balance |
| 6061 | 0.40–0.80 | 0.70 | 0.15–0.40 | 0.15 | 0.80–1.20 | 0.04–0.35 | 0.25 | Al balance |
Conductivity note: 1070 ≈ 63.3% IACS, 1060 ≈ 62.5%, 1050 ≈ 61.8% — iron is the main thief. For transformer and reactor windings, order 1060/1070 with an electrical resistivity certificate, not just chemistry. For anodised architectural trim, low Fe avoids streaking — see the anodizing guide.
6. Mechanical Properties by Temper (typical ranges — confirm on mill certificate)
| Alloy-Temper | UTS (MPa) | YS (MPa) | Elong. (%) | Typical Strip Use |
|---|---|---|---|---|
| 1050-O | 60–95 | ≥ 20 | 25–38 | Wound gaskets, deep forming |
| 1060-O | 60–90 | ≥ 15 | 28–40 | Transformer winding |
| 1070-O | 55–85 | ≥ 15 | 30–42 | Capacitor / conductor strip |
| 1100-H14 | 110–145 | ≥ 95 | 3–8 | Nameplate, trim |
| 3003-O | 110–165 | ≥ 40 | 18–30 | Fin stock, deep channels |
| 3003-H14 | 140–200 | ≥ 115 | 2–8 | Duct, general strip |
| 3004-H19 | ≥ 245 | ≥ 215 | 1–4 | Rigid formed strip |
| 3105-H24 | 195–245 | ≥ 150 | 2–7 | Siding and roofing trims |
| 5052-O | 170–215 | ≥ 65 | 15–25 | Cable armour, deep forming |
| 5052-H32 | 215–265 | ≥ 160 | 7–14 | Truck panels, brackets |
| 5052-H34 | 235–285 | ≥ 180 | 6–12 | Marine trim, general structural |
| 5083-O | 275–350 | ≥ 125 | 14–20 | Marine, cryogenic strip |
| 6061-T4 | ≥ 205 | ≥ 110 | 14–16 | Formed then aged |
| 6061-T6 | ≥ 290 | ≥ 240 | 6–10 | Structural strip after ageing |
How to read it: stepping from O → H12 → H14 → H16 → H18 trades roughly 25–40 MPa of strength per step for elongation. Forming-heavy jobs stay O/H22; rigid formed parts go H14/H24; spring-temper roll forming wants 5xxx H32/H34.

7. Width, Thickness & Tolerance Classes
This is where strip suppliers actually compete. The tolerance class you buy should be driven by your process, not by habit:
| Parameter | Commodity Class | Precision Class | Decide By |
|---|---|---|---|
| Width tolerance | ±0.25–0.50 mm | ±0.05–0.10 mm | Print/roll-form registration; winding lay precision |
| Thickness tolerance | ±5–8% of gauge | ±2–3% of gauge | Weight-based billing vs forming clearance |
| Burr height | ≤ 10% of thickness | ≤ 5% of thickness (deburred) | Edge cracking in forming; insulation of windings |
| Camber | ≤ 2 mm/m | ≤ 1 mm/m | Web tracking on long lines |
| Out-of-flat | ≤ 4 mm | ≤ 2 mm | Feeding without wrinkles |
| Coil set / cast | Moderate | Controlled by stress-relief anneal | Unwind stability |
Precision costs money but saves more. A ±0.05 mm width class typically adds 5–10% to strip price; one jam per shift on a 300 m/min roll former costs far more. If you do not know your class, send us the downstream process and we will recommend it — this is the single highest-value conversation in a strip RFQ.
8. Edge Quality: Slit, Deburred, Rounded, Square
| Edge Type | How Produced | Typical Spec | Where Required |
|---|---|---|---|
| Mill slit (natural) | Standard rotary knives | Burr ≤ 10% t | Construction trim, ducting |
| Deburred | Knife set-up + edge conditioning | Burr ≤ 5% t | Cable armour, handling-safe trims |
| Rounded / radiused | Edge rolling passes | R ≥ 0.3–0.8 mm | Transformer windings (insulation protection), wiper strips |
| Square / drawn | Drawing through shaping dies | Straight, work-hardened | Precision winding, zipper stock |
| Anodising-quality edge | Deburred + surface pre-treatment | No die lines after anodise | Visible architectural trim |
For edge-wound transformer and reactor strip, edge radius matters electrically: a sharp burr concentrates field and punctures inter-turn insulation. Winding shops typically demand rounded edges with radius ≥ half the insulation-paper thickness — put that on the PO in millimetres, not adjectives. For exposed architectural strip, note that anodising amplifies edge defects; see the anodizing guide and decorative finishes guide.
9. Applications by Industry: What the Pros Order
| Industry | Typical Product | Alloy / Temper | Size (t × w) | Notes |
|---|---|---|---|---|

| HVAC & heat exchangers | Fin stock, duct connectors | 3003-H14 / 8011 | 0.08–0.3 × 50–300 mm | Coated or bare; see fin-stock guide |
| Electrical busbar | Flexible laminated busbar | 1050 / 1060 | 0.5–3 × 20–200 mm | See busbar guide for ampacity |
| Roll forming | Channels, angles, slats, trims | 3003 / 5052 / 6061 | 0.4–3.0 × 20–600 mm | Precision width ±0.05–0.1 mm |
| Shutters & blinds | Slat strip | 3005 / 3105 / 5052 | 0.2–0.5 × 25–100 mm | Coated (PE/PVDF), both sides |
| Automotive | Heat shields, gaskets, trim | 3003 / 5052 | 0.1–2.0 mm | See automotive lightweighting guide |

Wider context for the biggest strip markets: 3003 for HVAC & heat exchangers, aluminum busbar guide, heat sink alloys (6063 vs 6061 vs 1050), automotive & EV lightweighting, and 3003 in EV battery systems. For perforated trim and acoustic panels slit from strip, see the perforated sheet guide.
10. Surface Treatments: Mill, Coated, Anodized, Embossed, Polished
| Finish | Spec Highlights | Typical Application |
|---|---|---|
| Mill finish | As-rolled, no treatment | Industrial strip, armour, winding |
| PE coating (10–18 µm) | Interior durability, any RAL | Blind slats, interior trims |
| PVDF coating (25–30 µm) | Exterior 15–20 yr colour warranty | Roofing trims, facade strips |
| Anodized (Ag2/E6 etc.) | 5–25 µm oxide, colour-stable | Architectural trim, consumer goods |
| Embossed (stucco/diamond) | Diffuses light, hides oil canning | Insulation jacketing, decorative |
| Brushed / mirror | Mechanical polishing | Consumer electronics, signage |
| Lubricated (dry-film) | 0.5–2 g/m² forming oil | Deep roll-forming lines |
Coating and anodising details — film thickness classes, colour matching, warranties — are covered in the surface finishing guide, anodizing complete guide and decorative aluminum finishes guide. For marine-exposed strip, check alloy suitability in the corrosion resistance guide before choosing an anodised finish.
11. Roll Forming & Bending: Minimum Radii and Springback
| Alloy-Temper | Min Bend Radius (90°, t = thickness) | Springback Tendency | Forming Notes |
|---|---|---|---|
| 1050/1060-O | 0 t | Low | Forms freely; watch galling |
| 3003-O | 0 t | Low | Excellent for channel forming |
| 3003-H14 | 0.5–1 t | Moderate | Standard trims and ducts |
| 5052-O | 0 t | Low-moderate | Deep channels, cable armour |
| 5052-H32 | 1–1.5 t | Moderate | Truck panels; overbend 3–6° |
| 5052-H34 | 1.5–2 t | Moderate-high | Stiffer sections; watch edge cracking |
| 5083-O | 1 t | Moderate | Marine sections |
| 6061-T4 | 1.5–2 t | Moderate | Form first, then age to T6 |
| 6061-T6 | 2.5–4 t | High | Avoid post-ageing bends < 2.5 t |
Springback scales with yield strength — 6061-T6 rebounds roughly twice as much as 5052-H34. Design the overbend into the tool, not the operator. Edge condition interacts too: slit edges with burrs crack on the tension side of the bend, so deburr before tight radii. The full method, tooling and defect gallery live in the bending & forming guide; welding formed strip sections is covered in the welding guide.
12. Weight & Length Calculations for Strip
Lineal weight: kg/m = width(mm) × thickness(mm) × 2.71 ÷ 1000.
| Size (t × w) | kg/m | m per Tonne | Typical Coil (OD 800 / ID 505) | Coil Weight |
|---|---|---|---|---|
| 0.5 × 50 mm | 0.068 | 14,760 m | ≈ 3,400 m | ≈ 231 kg |
| 1.0 × 100 mm | 0.271 | 3,690 m | ≈ 1,160 m | ≈ 315 kg |
| 1.5 × 150 mm | 0.610 | 1,640 m | ≈ 770 m | ≈ 470 kg |
| 2.0 × 200 mm | 1.084 | 922 m | ≈ 580 m | ≈ 629 kg |
| 3.0 × 300 mm | 2.439 | 410 m | ≈ 385 m | ≈ 939 kg |
| 4.0 × 400 mm | 4.336 | 231 m | ≈ 290 m | ≈ 1,257 kg |
| 6.0 × 600 mm | 9.756 | 103 m | ≈ 195 m | ≈ 1,900 kg |
Estimate coil length from OD/ID with the ring-area method — full formulas and a worked example set are in the aluminum weight calculation guide. Buying tip: for weight-based invoices, agree whether thickness bills on nominal or measured average gauge; at ±5% tolerance that difference is worth 5% of the metal bill.
13. Standards, Certification & Acceptance Testing
| Standard | Scope | We Supply |
|---|---|---|
| ASTM B209 | Sheet & strip, US market | Chemistry + mechanical certificates |
| EN 485-1/-2/-4 | European sheet/strip, tolerances | Dimensional report per coil |
| JIS H4000 | Japanese market | On request |
| GB/T 3880 | Chinese national standard | Default mill certification |
| EN 10204 3.1 | Inspection document with actual results | Every shipment |
| ASTM B449 / EN 13601 | Electrical conductor strip | Resistivity (% IACS) certificate |
On receipt, quick checks that catch 90% of problems: measure width at 3 points along the coil (tolerance drifts with knife wear), check burr with a feeler gauge, verify camber against a straightedge on a 2 m run, and confirm temper by comparing hardness/UTS against the certificate. Pay attention to the 5052 vs 5083 distinction if marine grade is specified — the wrong 5xxx alloy on a salt-exposed trim is a warranty claim waiting to happen.
14. Strip Price Drivers
| Component | Share of Invoice | What Moves It |
|---|---|---|
| LME/SHFE metal + premium | 60–75% | Exchange price, regional ingot premium |
| Slitting conversion | 8–15% | Precision width class, edge treatment, narrow widths (more knives per pass) |
| Alloy premium | 0–10% | 1070/1060 purity vs 3105 commodity grades |
| Finishing | 0–20% | PE/PVDF coating, anodising, embossing |
| Packing & freight | 3–8% | Wooden crates, coil weight vs container limits |
Narrow strips cost more per kilo than wide: a 600 mm pass yields ten 60 mm strips but thirty 20 mm strips, so knife time and scrap edges scale with total cut metres. Volume leverages this — full master-coil campaigns (2–8 t per alloy) get the best conversion pricing. Track metal with the price trends guide and landed-cost mechanics with the China sourcing guide.

Frequently Asked Questions About Aluminum Strip
What is the difference between aluminum strip and aluminum coil?
Strip is simply slit coil below roughly 600 mm width. Chemically and mechanically it is the same product — the difference is the slitting operation and the tighter width/edge specs that come with it.
What widths and thicknesses can HXM supply?
Widths from 6 mm to 600 mm slit (master coil up to 2,650 mm available), thickness 0.1–6.0 mm. Precision width class down to ±0.05 mm on selected gauges.
Which alloy is best for transformer winding strip?
1060-O or 1070-O with rounded edges. Purity drives conductivity (62–63% IACS), and the soft O temper lets the winding machine form tight, workable loops. Always order with an electrical resistivity certificate.
What edge condition should I order for roll forming?
Deburred (burr ≤ 5% of thickness) for anything forming into visible or handled products; natural slit is acceptable for construction trim. Rounded edges are mandatory for transformer windings.
What is a realistic width tolerance for precision strip?
±0.05–0.10 mm is standard precision class; ±0.25–0.50 mm is commodity class. Choose precision if your process prints, registers or winds — the 5–10% price premium pays back in uptime.
Can I get color-coated aluminum strip?
Yes — PE (interior) and PVDF (exterior) coatings in RAL colours, 10–30 µm film on one or both sides, typically on 3xxx/5xxx alloys for blinds, slats and trims.
What is the difference between 3003 and 5052 strip?
5052 (Al-Mg) is roughly twice as strong and far more corrosion-resistant in marine/salt environments; 3003 (Al-Mn) is cheaper, forms more easily and is the default for HVAC and general trims. See our 3003 vs 5052 comparison for the full trade-off.
Is 6061 strip available in T6 temper?
Yes. For formed parts, order 6061-T4, form, then age to T6 — bending T6 strip below a 2.5–4× thickness radius risks cracking. Our 6061-T6 guide covers the heat-treatment sequence.
How do I calculate the weight of a strip coil?
Weight per metre = width(mm) × thickness(mm) × 2.71 ÷ 1000 kg. For a wound coil, use the ring-area method: length ≈ π × (OD² − ID²) ÷ (4 × thickness) in consistent units. Full formulas are in our weight calculation guide.
What is the MOQ and lead time?
MOQ 500 kg per alloy-gauge-width combination. Stock items ship in 7–10 days; precision slitting or coated strip runs 12–20 days.
Which strip alloys are suitable for outdoor architectural trim?
3105-H24 and 3003 for coated trims; 5052 near marine exposure; anodised 5005-class for visible facades. Check the corrosion guide for the environment-specific alloy notes.
What certificates come with each shipment?
EN 10204 3.1 mill certificate with actual chemistry and mechanical results, dimensional report per coil, and resistivity certificates for electrical grades.
Do you supply strip with paper interleaving?
Yes — paper interleaving is available for anodising-quality and cosmetic trim strip to prevent transit scratches; specify it in the RFQ as it affects coil OD.
Can strip be supplied as cut-to-length blanks instead?
Yes, but then it is sold as sheet. If your process is discrete stamping, blanks from our sheet line are usually more economical; continuous feeding stays as strip.
How is strip packed for sea freight?
Eye-to-sky coils on wooden cradles inside fumigated (ISPM 15) crates with VCI paper, end protection and humidity indicators; multiple coils per crate to maximise container utilisation.
Which alloys weld well after forming?
All 1xxx/3xxx/5xxx strip welds well (5356 or 4043 filler depending on alloy); 6xxx needs post-weld strength consideration. Filler selection is covered in our welding guide.
