2A12T451 aluminum alloy pre-stretching plate production process

2A12 is AL-CU-MG hard aluminum alloy, the main alloy composition: w (cu) 3.8% ~ 4.0% w (mg) 1.2% ~ 1.8% w (mg) 0.3% ~ 0.9%. He is a heatable aluminum alloy It has high strength after solution treatment and natural aging, but its corrosion resistance and welding performance are poor. The alloy has good processing properties, and the production process of 2A12T451 aluminum alloy tensile sheet is as follows:
