Product introductionï¼5a02 aluminum forging bar are Al-Mg series anti-rust aluminum, with high fatigue strength and high plasticity
5a02 aluminum alloy is Al-Mg series anti-rust aluminum, 5a02 aluminum alloy has higher strength, especially higher fatigue strength; high plasticity and corrosion resistance, similar to 3A21 in this respect; heat treatment can not be strengthened, use resistance welding and atom Hydrogen welding has good weldability, and there is a tendency to form crystal cracks during argon arc welding; the alloy has good machinability under cold work hardening and semi-cold work hardening, and poor machinability under annealed state and can be polished.
Chemical composition of 5a02 aluminum forging bar:
Silicon Si: 0.40 Iron Fe: 0.40
Copper Cu: 0.10 Manganese Mn: 0.15-0.40 or Chromium Cr: 0.15-0.40
Magnesium Mg: 2.0-2.8 Iron + Silicon Fe + Si: 0.6 0 Titanium Ti: 0.15
