| 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. | 375~460 |
