The commonly used die-casting aluminum alloy in die-casting processing plants usually annoys many die-casting purchasers, that is, they can't tell which types of aluminum alloy are the materials that can be cast for real die-casting aluminum products. Now I think you have sorted out the following contents:

First of all, die-casting aluminum alloy is divided into:

Medium and low strength and high strength: Al-Si-Cu, Al-Si-Mg, Al-Si-Cu-Mg, Al-Zn, etc.

Aluminum alloy die casting generally uses ADC12 Aluminum Alloy (Japanese brand), A356 aluminum alloy. A356 is generally made - automotive parts, ADC12 Aluminum alloy is generally made - general parts. The specific requirements of the final product on materials, including air tightness and hardness.

Aluminum alloy die casting can be divided into medium and low strength (such as y102 in China) and high strength (such as Y112 in China) according to performance. At present, die casting aluminum alloys for industrial application mainly include the following series: Al Si, Al Mg, Al Si Cu, Al Si mg, Al Si Cu mg, Al Zn, etc.

The improvement of mechanical properties of die-casting aluminum alloy is often accompanied by the reduction of casting process performance. This contradiction is more prominent in some aspects due to the characteristics of high-pressure rapid solidification of pressure casting. Therefore, it is difficult to carry out solid solution heat treatment for general die-casting parts, which restricts the improvement of mechanical properties of die-casting aluminum alloy Vacuum die casting is an effective way to improve the mechanical properties of alloys, but it is still difficult to widely use, so the development of new die-casting aluminum alloys has been carried out.
