Note: H1x tempers are strain-hardened only. H2x are strain-hardened then partially annealed. H3x are strain-hardened then stabilized by low-temperature heating. 3003 does NOT use T-series tempers (T3, T4, T5, T6, T7, T351, T451, T651, T851) — these apply only to heat-treatable alloys (2xxx, 6xxx, 7xxx series).

Product-Specific FAQ
Frequently asked questions about 3003 aluminum coil. Click to expand each answer.
What is 3003 aluminum coil?
3003 aluminum coil is a non-heat-treatable Al-Mn alloy coil containing 1.0-1.5% manganese. It offers good corrosion resistance, excellent formability, and moderate strength, conforming to ASTM B209. It is one of the most widely used aluminum coil alloys for roofing, HVAC, insulation, and general fabrication.
What is the most commonly used temper for 3003 aluminum coil?
H14 is the most common temper for 3003 aluminum coil, offering a good balance of strength (~150 MPa UTS) and formability. It is the standard choice for roofing, gutters, HVAC ducts, and insulation jacketing. O temper is used when maximum formability is required for deep drawing.
What is the difference between 3003-H14 and 3003-H24 aluminum coil?
Both have similar mechanical properties (UTS ~150 MPa), but H14 is strain-hardened only, while H24 is strain-hardened then partially annealed (stabilized). H24 is preferred for applications involving elevated temperature service, as it retains mechanical properties better at higher temperatures. H14 is more common for general use.
Is 3003 aluminum coil suitable for roofing and gutters?
Yes. 3003 H14 is one of the standard materials for roofing sheets and rainwater gutters. It offers excellent atmospheric corrosion resistance (20+ year service life outdoors), good roll-forming capability, and accepts pre-painting (PVDF/polyester) for architectural finishes. Thicknesses of 0.4-1.2 mm are typical.
Can 3003 aluminum coil be welded?
Yes. 3003 has excellent weldability using GTAW (TIG), GMAW (MIG), resistance welding, and friction stir welding. Recommended filler wires are 4043 (Al-Si) or 4047. Gas welding and brazing are also possible. Welding reduces strength in the heat-affected zone but does not significantly affect corrosion resistance.
What thicknesses and widths are available?
Typical coil thickness ranges from 0.2 mm to 8.0 mm, with widths from 100 mm to 2,000 mm. Specific ranges depend on HXM’s production capability. Please contact us with your required thickness, width, and temper for confirmation.
What is the difference between 3003 and 5052 aluminum coil?
3003 is an Al-Mn alloy with moderate strength (~150 MPa UTS) and lower cost, ideal for roofing, HVAC, and insulation. 5052 is an Al-Mg alloy with higher strength (~230 MPa UTS), better marine/saltwater corrosion resistance, and higher cost, preferred for marine, fuel tanks, and structural applications.
What is the difference between 3003 and 3004 aluminum coil?
3003 contains only Mn (1.0-1.5%). 3004 adds Mg (0.8-1.3%) alongside Mn, giving it higher strength (~180 MPa UTS) than 3003. 3004 is primarily used for beverage can bodies and deep-drawn containers, while 3003 is preferred for building and HVAC applications. Both have similar corrosion resistance.
Can HXM Aluminum provide slit coils and custom coil weights?
Yes, we provide slitting to customer-specified widths and can produce custom coil weights. Please specify your required slit width, coil ID, and target coil weight when requesting a quotation.
What information is required to request a quotation?
Please provide: (1) Alloy and temper, (2) Thickness, (3) Width, (4) Coil ID, (5) Coil weight or total quantity, (6) Surface finish, (7) Application, (8) Order quantity, (9) Destination port. The more complete your specifications, the faster and more accurate our quotation.
Is a Mill Test Certificate available?
Yes. A Mill Test Certificate (EN 10204 3.1) is provided with each shipment, reporting chemical composition and mechanical properties. EN 10204 3.2 certification by a third-party inspection agency can also be arranged upon request.
What affects the price of 3003 aluminum coil?
Price is primarily driven by the London Metal Exchange (LME) aluminum price, plus processing premium for temper, slitting, surface finish, and coating. Coil weight, order quantity, packaging requirements, and freight to destination port also affect the final quoted price.
