3003 Aluminum Coil
3003 aluminum coil is an aluminum-manganese alloy, belonging to the 3000 series (or 3xxx series). This alloy cannot be strengthened by heat treatment but can be improved through cold working. Like other aluminum-manganese alloys, 3003 aluminum coil has moderate strength, good machinability, and excellent corrosion resistance.
Common processing methods for 3003 aluminum coil include rolling and extrusion, but it is not suitable for casting. It is widely used in applications requiring good formability and weldability, such as gutters, downspouts, roofing, and wall panels.
3003 aluminum alloy is a widely used aluminum-manganese alloy that offers higher strength and better corrosion resistance compared to the 1100 alloy. It is suitable for various applications requiring excellent formability and weldability.
3003 aluminum coil is based on pure aluminum with the addition of 1.0–1.5% manganese, which significantly improves the material’s strength and corrosion resistance while maintaining lightweight characteristics (density approximately 2.73 g/cm³).
- Non-heat treatable: Strength is increased through cold working (strain hardening) rather than heat treatment.
- Main standards: ASTM B209, ISO 6361, and EN-AW 3003.
3003 aluminum coil is a widely used material, highly regarded for its adaptability across industries. Its combination of moderate strength, corrosion resistance, and ease of manufacturing makes it an indispensable material in applications ranging from construction to energy storage.
