The Influence of Strength and Material on Quality of Aluminum Alloy Die Castings

The research on the mechanical properties of aluminum alloy die-casting parts mostly focuses on test pieces and test rods, but the research on the effects of defects, microstructure, and solid solution of components related to product performance is not sufficient, resulting in many unsafe factors in product design. With the increasing frequency of opening up to the outside world, the ADC12 aluminum alloy in the Japanese JIS standard has become a major die-casting material used in domestic general production. Therefore, it is necessary to conduct analysis and research on the material, host, and mechanical properties of materials represented by ADC12 alloy. And aluminum alloy die castings are made of ADC12 aluminum alloy according to the Japanese JIS standard as one of the main raw materials for die casting.

Discuss the influence of strength and material on the quality of aluminum alloy die castings, especially the influence of magnesium, silicon, and iron components on mechanical properties. The tensile strength remains basically unchanged with the increase of magnesium; The addition of copper shows an increasing trend in its tensile strength. Silicon can significantly improve fluidity, but it is harmful to cutting performance. The influence of iron basically increases hardness, reduces elongation and impact toughness.
