7A03 aluminum round bar rod

Dec 19, 2022

7A03 aluminum alloy is super hard rivet alloy.The plasticity in quenching and artificial aging is sufficient to make rivets riveted;Aluminum alloy 7A03 can be strengthened by heat treatment and resist shear at room temperature
High strength, good corrosion resistance and machinability.7A03 aluminum alloy rivet without heat treatment time limit.

Standard GB/T 3196-1982 for 7A03 aluminum alloy

Chemical composition of 7A03 aluminum alloy round bar rod

Copper Cu: 1.8 ~ 2.4 aluminum Al residual silicon Si 0.20 magnesium Mg: 1.2 ~ 1.6 zinc Zn: 6.0 ~ 6.7 manganese Mn: 0.10

Titanium Ti: 0.02 ~ 0.08 Cr: 0.05 Fe: 0.000 ~ 0.200 note: single: 0.05Total: 0.10 or less

7A03 aluminum bar rod’s mechanical properties: shear strength 284 note: the shear resistance of wires after solution heat treatment has been reduced to basically stable state after natural aging
