Introdunction
7A04 Aluminum Plate is mainly composed of ultra-high-strength aluminum alloy composed of aluminum, zinc, magnesium and copper. It is also called super-hard aluminum. 7A04 Aluminum Plate is quite mature among super-hard aluminum. It is an alloy that has been used for a long time and is widely used. It has high strength and is strengthened by heat treatment. The effect is good. Alloy spot welding has good weldability and good machinability after heat treatment.
