3003 Aluminum Coil
3003 aluminum coil is a manganese-based aluminum alloy known for its excellent corrosion resistance, good formability, and moderate mechanical strength. It is widely used in HVAC systems, roofing applications, thermal insulation, packaging, and various industrial fabrication processes where durability and workability are required.
Compared with 1100 series aluminum, 3003 aluminum coil contains a small addition of manganese, which improves its strength by approximately 15–20% while maintaining excellent ductility and forming performance. This balance of strength and workability makes it one of the most commonly used non-heat-treatable aluminum alloys in general engineering applications.
3003 aluminum coil and sheet products are typically manufactured in compliance with internationally recognized standards, including ASTM B209, EN AW-3003, ISO 6361, and AMS-QQ-A-250/2. These specifications ensure consistent mechanical properties, dimensional accuracy, and material reliability for industrial and engineering applications requiring strict quality control.

Typical Tempers of 3003 Aluminum Coil
3003 aluminum alloy cannot be strengthened by heat treatment, and its strength is mainly achieved through cold working (strain hardening). Common tempers include O, H12, H14, and H22, with the 3003-H14 condition offering a good balance between strength and formability. This alloy can be formed by various processes such as deep drawing, stretching, spinning, bending, welding, and brazing.
- O (Annealed): Fully annealed condition with maximum ductility and softness. Ideal for deep drawing, complex forming, and applications requiring high plasticity.
- H12 (Quarter Hard): Lightly strain-hardened temper offering a balanced combination of strength and formability. Commonly used in roofing and general sheet metal fabrication.
- H14 (Half Hard): The most widely used temper for 3003 aluminum coil. Provides good strength, corrosion resistance, and excellent workability. Suitable for HVAC ducting, roofing, siding, and gutters.
- H16 (Three-Quarter Hard): Higher strength than H14 while maintaining acceptable formability. Used in exterior panels, cladding systems, and structural sheet applications.
- H18 (Full Hard): Maximum strain-hardened condition in standard production. Offers high strength and rigidity with reduced formability. Common in roofing sheets and rigid architectural components.
- H24: Strain-hardened and partially annealed temper that provides a balance between strength and ductility. Frequently used in HVAC systems, decorative panels, and outdoor applications requiring stability.
- H19 (Extra Hard): Very high strength temper with limited formability. Suitable for applications requiring maximum rigidity, such as structural panels and industrial coverings.
Typical specifications of 3003 aluminum coil include thickness ranging from 0.2 mm to 3.0 mm and width from 600 mm to 2000 mm, depending on customer requirements and production capability.
