3103
UNS A93103
Description
Aluminum alloy 3103 is a non-heat treatable wrought alloy whose properties are very close to 3003. The typical properties are medium strength, good resistance to atmospheric corrosion and good weldability. The alloy has improved mechanical properties, especially at elevated working temperatures when compared with 1000 series aluminum alloys. Aluminum alloy 3103 is usually used in aerospace, oil and gas industry and automotive sector amongst others.
