Aluminum process properties
Forming properties
The alloy has good hot process plasticity. The forging and die forging temperature is ~, and the thermal deformation with a deformation rate of % is carried out within this temperature range.
The cold stamping performance is related to the alloy state. The cold stamping performance in the annealed state is good, followed by the annealed state, and not good in the / state.
Welding properties
The alloy has good performance in gas welding, arc welding, resistance welding, spot welding and seam welding. It has a tendency of crystallization cracks during argon arc welding. The brazing performance is good, while the soft soldering performance is poor.
The weld has high strength and plasticity, and the weld strength reaches %~% of the strength of the base metal. However, the air tightness of the weld is not high. It is recommended to use alloy as solder, which can improve its air tightness and eliminate the tendency of cracks.
Machining performance
The cutting performance of the alloy in the annealed state is not good, but it is improved in the cold work hardened state
