Introduction to 5A02 Aluminum Rod Factory

The 5A02 aluminum rod factory's 5A02 aluminum rod is made of Al Mg anti rust aluminum. Compared with 3A21, the 5A02 aluminum rod has higher strength, especially higher fatigue strength; High plasticity and corrosion resistance, similar to 3A21 in this regard; The heat treatment of 5A02 aluminum rod cannot be strengthened, and resistance welding and atomic hydrogen welding have good weldability. There is a tendency to form crystalline cracks during argon arc welding; The alloy has good machinability in both cold work hardening and semi cold work hardening states, but poor machinability in annealing state and can be polished.

1) Uniform annealing of 5A02 aluminum bars at 5A02 aluminum bar factory: heating at 440 ℃; Insulation for 12-14 hours; Air cooling.

2) Rapid annealing of 5A02 aluminum rods at 5A02 aluminum rod factory: heating at 350-410 ℃; The insulation time is 30-120 minutes; Air or water cooling.

3) High temperature annealing of 5A02 aluminum rods at 5A02 aluminum rod factory: heating at 350-420 ℃; When the thickness of the finished product is ≥ 6mm or<6mm, the insulation time is 2-10 minutes or 10-30 minutes; Air cooling.

4) 5A02 aluminum rod factory's 5A02 aluminum rod low-temperature annealing: heating at 250-300 ℃ or 150-180 ℃; The insulation time is 1-2 hours, air-cooled.

Status: Aluminum and aluminum alloy patterned plate (O state).
