Strength of aluminum alloy die casting

The research on the mechanical properties of aluminum alloy die castings mostly stays on test pieces and test rods. However, the research on the effects of defects, structure, and solid solution of components related to product performance is not sufficient, which leads to many problems in product design. factor. With the gradual and frequent 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 ordinary films. Therefore, it is necessary to carry out analysis and research on the material, host and mechanical properties of the alloy in ADC12 as a representative material. The Tianjin aluminum alloy die castings are based on the ADC12 aluminum alloy in the Japanese JIS standard as one of the main raw materials for die casting.

The influence of the strength and material of aluminum alloy die castings on quality is discussed, especially the influence of magnesium, silicon, and iron on mechanical properties is analyzed. The tensile strength of magnesium is basically unchanged with the increase; while the tensile strength of copper has a tendency to increase. Silicon can significantly improve fluidity, but silicon is harmful to machinability. The effect of iron basically increases hardness, reduces elongation and impact toughness.
