About Alloy
Aluminum alloy 3003 is a widely used general-purpose aluminum alloy with moderate strength and good workability. It is part of the 3xxx series of aluminum alloys, which are known for their excellent corrosion resistance and formability. Alloy 3003 is typically composed of aluminum, manganese, and a small amount of copper.
Corrosion Resistance: Alloy 3003 offers excellent resistance to atmospheric corrosion, making it suitable for outdoor and marine applications.
Formability: It has good formability, allowing for easy shaping and bending into various forms without cracking.
Weldability: Alloy 3003 is readily weldable using conventional methods, making it versatile for manufacturing processes that involve joining.
Strength: While not as strong as some other alloys like 6061 or 7075, 3003 offers sufficient strength for many structural applications.
Heat Treatment: It is not heat-treatable, meaning its mechanical properties are primarily achieved through cold working.
