AlSi7Mg Low pressure aluminum alloy casting

AlSi7Mg is a common and used aluminum alloy grade. It is called differently in international countries, such as in China ZL101, ISO-Al-Si7Mg (Fe), Japan AC4C, European standard is 42100, Germany is alsi7mg, Britain is LM25, USA is A356. Of course, they are all the same. This kind material could do heat treatment T5, T6 to increasing mechnical  needs, and its good applied for parts in low pressure, you’ll ask why?

The technical characteristics of low pressure casting:
1. The pressure and speed during casting can be adjusted, so it can be applied to various molds (such as metal type, part need sand core, etc.), casting various alloys and various sizes of castings. 0.02kg-30kg.
2. The metal liquid filling type is stable, and there is no splashing phenomenon, which can avoid the entrapment of gas and the flushing of the type wall and the core, and improve the qualification rate of the casting.
3. The casting is crystallized under pressure. The casting has compact structure, clear outline, smooth surface and high mechanical properties, which is especially beneficial for the casting of large thin or thick-walled parts.
4. Save the shrinking riser and increase the metal utilization rate to 90% to 98%.
5. Low labor intensity, good working conditions, simple equipment, easy mechanization and automation.
