Alloy Alloy series Main features Σb Value /MPa Temperature/℃
2A14 Al-Cu-Mg It's close to 2014. The main varieties are bars, profiles, forgings and plates, etc. It is suitable for high load parts with thick section. The welding performance of the alloy is good, and it does not show brittleness at the cold temperature. It can be used to make the welding parts under the cold working condition.

2A14 Welding performance
Alloy Resistance welding Melting welding Argon arc welding Note
2A14 Good Ok During welding, the tendency of heat crack is larger, so it is necessary to limit the content of iron impurities in the matrix, and the qualified filler can be obtained by using special filler.
