Product Description
3003 aluminum coil is an Al-Mn alloy known for its excellent corrosion resistance, especially in atmospheric and marine environments. It is a non-heat-treatable alloy, and its strength can be improved through cold working. This alloy is widely used in various industries due to its moderate strength, good formability, and weldability.

3003 aluminum coil is used in various applications due to its properties:
Food packaging containers, such as lunch boxes, cans, and bottle caps.
Building decoration materials, including aluminum ceilings, curtain wall panels, and aluminum alloy roof panels.
Coolers, radiators, and air conditioner heat exchangers.
Auto parts, including body panels, fuel tanks, and radiator covers.
High Corrosion Resistance: Resists corrosion under most common environmental conditions.
Good Formability: Can be processed into various shapes by cold rolling, cold drawing, deep drawing, shearing, and other processes.
Weldability: Easy to weld, achieving reliable welding connections by various methods.
Conductivity: Good electrical conductivity, suitable for electrical and electronic applications.
Packaging: Each aluminum coil is individually wrapped in a protective material such as plastic or kraft paper to prevent scratches or surface damage. Place individually wrapped coils in a strong outer packaging, such as a wooden box or pallet, for overall protection and support.
Handling: Use proper equipment, such as forklifts or cranes, to handle aluminum coils to prevent bending or deformation.
Storage: Store in a dry area, away from moisture and corrosive substances, to maintain the quality of the aluminum coil
