5052 Aluminum Alloy Process performance

- Apr 16, 2018 -

5052 Aluminum Alloy Process performance:
1. Formability
The 5052 Aluminum alloy is in good thermal state and has good plasticity. The forging and die forging temperature is 420~475 degrees C, and the thermal deformation of deformation rate >80% is carried out in this temperature range.
The cold stamping properties are related to the alloy state. The cold stamping properties of the annealed (O) state are good, the H32 and H34 states are second, and the H36/H38 state is not good.
2. Welding performance
The 5052 Aluminum alloy welding, arc welding, resistance welding, spot welding, seam welding performance is good, the crystallization tendency of two cracks in argon arc welding. The brazing performance is good, but the solderability is poor.
The strength and plasticity of the weld are high and the weld strength is 90%~95% of the base metal strength. But the tightness of the weld is not high. It is recommended to use 5A03 alloy as the solder, which can improve the air tightness and eliminate the tendency of cracks.
3. Machinability
The machinability of the 5052 Aluminum alloy in the annealed state is not good, while the cold work hardening state has improved.
