WHY ASTM A356,JIS AC4C, GB ZL101A Aluminum casting electric power parts need to do Heat Treatment？
Since the cast aluminum parts cannot meet the mechanical performance requirements during use, heat treatment is required. Its main purpose is to enhance the corrosion resistance, improve the mechanical properties of the alloy, improve the processing type, and obtain dimensional stability.
Most cast aluminum alloys need to be heat treated to further improve the mechanical properties and other use properties of the cast aluminum parts (except for the ZL102 of the Al-Si series, ZL302 of the Al-Mg series, and the ZL401 of the Al-Zn series).
The main role of heat treatment of cast aluminum parts:
1.Remove the internal stress caused by uneven cooling speed of the casting during crystallization and solidification due to the structure of the aluminum casting;
2.Improve the strength and hardness of cast aluminum parts, improve the metallographic structure, and ensure the plasticity and cutting performance and welding performance of the alloy;
3. Stabilize the structure and size of aluminum castings, prevent and eliminate high-temperature phase changes that cause volume changes;
4. Eliminate the crystallization and composition segregation of aluminum castings to make the structure uniform.
low pressure metal casting parts（0~100kg）, each enclosures must pass pressure test of shell strength, air tightness test SF6 gas test device, the indicators have reached the leading domestic level.
