Characteristics and scope of application:
7A03 aluminum alloy is an alloy used for superhard rivets. The plasticity during quenching and artificial aging is enough to allow rivets to be riveted; 7A03 aluminum alloy can be strengthened by heat treatment. It has high shear strength at room temperature, good corrosion resistance, and good machinability. 7A03 aluminum alloy rivets are not restricted by the time after heat treatment.
