5083 Precision-Slit Aluminum Strip: Widths to ±0.05 mm, Tempers, Coil Sourcing & Pricing

HXM slits 5083 aluminum strip from our own master coils: 0.15–6.0 mm thick, 3–1,300 mm wide, width tolerance to ±0.05 mm, in O / H12 / H14 / H16 / H18 / H32 / H34 tempers with burr-free slit edges. Strip is the form buyers choose when they need marine-grade corrosion resistance in narrow, tight-tolerance lengths — cable armouring, transformer and choke cases, marine panel stiffeners, gaskets and stamped brackets. MOQ 500 kg, EN 10204 3.1 certificate with every coil, quotation within 24 hours.

⚡ Quick Answer

5083 strip is simply 5083 coil slit to narrow width — the same 4.0–4.9 % Mg chemistry that makes 5083 the marine-grade benchmark, delivered in widths your stamping, winding or armouring line can feed directly. Pick O for deep forming and armouring, H32/H34 for stamped brackets and panels, H18 where maximum strip strength is needed. Because 5083 work-hardens faster than 5052, order it when your part needs 30 % more strength than 5052 strip in the same temper. See the full strip range for sibling alloys.

Why Specify 5083 as Strip — and When 5052 or 3003 Beats It

Strip buyers juggle three competing alloys. Here is the honest decision matrix our sales engineers use:

Factor	5083 strip	5052 strip	3003 strip
Strength (O temper)	275–350 MPa	170–215 MPa	110–130 MPa
Formability	Good (O/H12)	Excellent (O)	Excellent
Seawater corrosion	Outstanding	Excellent	Moderate — not for immersion
Cost per tonne	highest	mid	lowest
Work-hardening rate	high — strength rises fast with temper	moderate	low
Best for	marine hardware, cable armour in splash zones, high-load stamped parts	general formed parts, tanks, trim	transformer windings, HVAC, deep drawing

Rule of thumb: if the part sees seawater and load, 5083 strip pays for itself. If it only needs corrosion protection without structural load, 5052 strip is usually the smarter spend. For indoor electrical or HVAC work, 3003 strip wins on cost. Full alloy comparisons: 5052 vs 5083 buyer’s guide.

Chemical Composition (EN 573-3 / ASTM B209)

Element	Min (%)	Max (%)
Mg	4.0	4.9
Mn	0.40	1.00
Cr	0.05	0.25
Si	—	0.40
Fe	—	0.40
Cu	—	0.10
Zn	—	0.25
Ti	—	0.15
Other each / total	—	0.05 / 0.15
Aluminium	remainder	—

The high Mg + Mn combination is what gives 5083 strip its strength-per-micron advantage — critical when your design is thickness-limited but load-bearing.

Mechanical Properties by Temper (EN 485-2)

Temper	Tensile strength (MPa)	0.2% proof (MPa)	Elongation A50
O	275–350	≥125	≥16 %
H12	≥305	≥145	≥9 %
H14	≥340	≥230	≥6 %
H16	≥370	≥280	≥4 %
H18	≥410	≥330	≥3 %
H32	≥305	≥215	≥7 %
H34	≥340	≥250	≥5 %

Temper Selection by Application — and What Seawater Does to Strip

Application	Recommended temper	Reason
Cable armouring / interlocking	O	Maximum ductility — armour profiles form without edge cracking
Deep-formed cases & housings	O / H12	Formability first; strength recovers in final part geometry
Marine stiffeners & trims	H32 / H34	Structural stiffness on wide spans
High-strength stamped clips	H34	250 MPa proof strength holds fastener loads
Springs & retaining rings	H18	410 MPa class from work hardening alone
Welded strip assemblies	H32	Predictable HAZ behaviour with ER5356/5183 filler

Corrosion behaviour mirrors the plate data: 5083’s high-magnesium chemistry gives outstanding splash-zone and immersion performance, with copper held ≤0.10 % so no galvanic cells form inside your assembly. For armouring and marine trims we add lot-by-lot exfoliation-corrosion screening on request — same ASTM G34 protocol used on hull plate. Background: does aluminum rust? corrosion guide.

Slitting Capability — Width Tolerance, Edge Quality & Camber

Strip is a tolerance business. This is exactly what HXM’s slitting lines hold, coil after coil:

Attribute	Standard	Premium (on request)
Width tolerance	±0.05 mm	±0.02 mm
Burr height	≤ 0.05 mm	≤ 0.02 mm deburred
Camber	≤ 1.0 mm/m	≤ 0.5 mm/m
Edge condition	mill slit	round / deburred / drawn edge
Thickness tolerance	EN 485-3 normal	special class ±1 %
Coil set / twist	controlled by tension levelling	stress-relieved anneal

Buyer pain point solved: feeding problems on progressive dies and winding machines almost always trace back to camber and burr, not alloy. Specify the premium column and we laser-measure every delivered coil — with the measurement report attached to the certificate.

Strip Weight, Coil Build-Up & Container Loading

Freight and inventory planning numbers buyers ask for before the PO:

Strip size (mm)	Weight per 100 m (kg)	Typical slit coil (kg)	Coils per 20 ft container
0.3 × 25	20.3	100–200	~150 coils
0.5 × 50	67.8	200–400	~80
0.8 × 100	217	300–600	~50
1.0 × 125	339	400–800	~38
1.5 × 200	813	600–1,200	~24
2.0 × 300	1,626	1,000–2,000	~14
3.0 × 400	3,252	1,500–3,000	~8

Weight formula: kg/m = thickness (mm) × width (mm) × 0.00271. The full formula set for every product form is in our aluminum weight calculation guide.

From Master Coil to Your Slit Width — One Traceable Heat

HXM strips are slit from coils rolled in our own mill — not traded semis from a third party. The advantage shows up in your certificate file: one heat number links casting chemistry, rolling mechanicals and slit-width measurement from melt to delivery.

Where 5083 Strip Wins — Application by Application

Application	Typical size	Why 5083 strip
Cable armouring for marine & offshore	0.3–0.8 mm × 10–32 mm	withstands splash-zone corrosion; interlocks without cracking (O temper)
Marine panel stiffeners & edge trims	1.0–3.0 mm	same alloy as the 5083 plating it joins — no galvanic mismatch
Transformer & reactor case components	0.5–2.0 mm	non-magnetic, corrosion-proof housings for humid environments
Stamped brackets & clips (marine/industrial)	0.4–3.0 mm, H32/H34	strength holds threads and fasteners better than 5052
Gaskets & shims	0.15–0.5 mm	stable at temperature, won’t corrode against steel flanges
Springs & retaining parts	0.3–1.5 mm, H18	high work-hardened strength
Honeycomb edge closeouts	0.3–1.0 mm	pairs with our honeycomb panel production

Forming, Stamping & Welding 5083 Strip

Process guidance that saves buyers weeks of trial and error:

Process	Guideline for 5083 strip	Watch out for
90° bend, O temper	radius ≥ 1.5 × thickness	keep bend axis transverse to rolling direction
90° bend, H32	radius ≥ 2.5 × thickness	heat-soften for tighter radii
Deep drawing	O temper only, slow speeds	blank holder pressure — 5083 galls more than 5052; use proper lubricant
Stamping, H32/H34	clearance 8–10 % of thickness	work-hardening raises punch wear vs 5052
MIG/TIG welding	ER5356 or ER5183 filler	thin strip distorts — fixture and skip-weld
Anodising	anodises cleanly; slightly greyer than 6061	matte match against other alloys is imperfect

Frequently Asked Questions About 5083 Aluminum Strip

What width tolerance can HXM hold on 5083 strip?

±0.05 mm is standard on all slit widths; ±0.02 mm is available for die-critical applications. Every coil is laser-measured and the report ships with the mill certificate.

What is the thinnest 5083 strip you produce?

0.15 mm is our standard minimum for 5083. Below that, consider 8011/8021 foil or a 5052 strip at heavier gauge — 5083’s work-hardening makes ultra-thin gauges technically possible but rarely economic.

5083 strip vs 5052 strip — which should I buy?

Choose 5083 when the part is load-bearing or sits in a splash/immersion zone: it delivers roughly 30 % more strength at equal temper. Choose 5052 for general forming where the extra strength isn’t needed — it’s more formable and costs less. Comparison guide: 5052 vs 5083 for marine applications.

Which temper works for deep drawing 5083 strip?

O temper only. 5083 work-hardens quickly, so H32 and above will crack on deep draws. For severe drawing applications, 5052-O or 3003-O draw more forgivingly — send the part drawing and our engineers will confirm.

Can 5083 strip be welded without losing corrosion resistance?

Yes. Weld with ER5356 or ER5183 filler; the joint retains the alloy’s inherent seawater corrosion resistance. The heat-affected zone softens to near-O strength — design weld joints accordingly.

Do you supply deburred or rounded-edge strip?

Yes — deburred edge (burr ≤ 0.02 mm) and rounded/drawn edges are available on request for winding, armouring and edge-contact applications. Add roughly 3–6 % to strip price.

What is the MOQ for a custom slit width?

500 kg per width-thickness combination. If your width can be slit from one of our running stock master coils, trial quantities can be smaller — ask our sales desk for current running widths.

How are slit coils packed for export?

Moisture-barrier wrapped with desiccant, on ISPM-15 wooden pallets or in crates, steel-strapped with edge protection, and labelled with alloy/temper/size/heat number. Container loading plans are sent before shipment.

What certificates come with 5083 strip?

EN 10204 3.1 mill certificate with actual chemistry and mechanicals, plus the slit-width laser measurement report. Marine class certificates (DNV/ABS/LR/BV/CCS) are available for offshore armouring orders.

Can you match 5083 strip to the plate or coil already in my build?

Yes — strip is slit from the same 5083 production system as our plate and coil, so heat-to-heat chemistry and temper logic stay consistent across your assembly. One certificate system covers all forms.

What is the lead time for custom 5083 strip?

12–25 days production depending on width and temper, plus sea transit 25–35 days. Widths slit from running stock masters can ship significantly faster — check availability before planning your production run.

Is 5083 strip suitable for transformer winding cores?

For case components, brackets and busbar supports, yes — it’s non-magnetic and corrosion-proof. For the winding conductor itself, electrical-grade alloys (1350, 1050, 1060) or 3003 transformer strip are the correct choice; 5083’s high Mg hurts conductivity.
