EN AW-3003 Aluminum Alloy – Corrosion-Resistant & Easy Weldability

Aluminum EN AW-3003 is a popular alloy that offers customers very good atmospheric corrosion resistance and moderate strength. Aluminum 3003 offers good machinability for aluminum alloys, though it is not heat treatable. Unlike other aluminum alloys, EN AW-3003 is weldable by conventional welding methods. It also takes cold and hot working well and has generally better mechanical properties when compared to 1000 series aluminum alloys.
