380压铸合金成分的变化对力学性能的影响

Influence of Chemical Composition Change of 380 Aluminum Alloy on Mechanical Properties

试验分析了 3 80压铸合金化学成分的不同配比对力学性能的影响。结果表明高合金含量配制的 3 80铝合金与低合金含量配制的 3 80铝合金相比 ,前者抗拉强度、屈服强度及硬度高 ,而后者伸长率高 ,标准的 3 80铝合金成分则在二者之间。实际应用中 。

Different rations of chemical composition of 380 die casting alloy are analyzed.The results show that 380 alloy with high alloy has a higher tensile strength,yielding strength and hardness while 380 with low alloy has higher elongation.Chemical composition of 380 alloy with excellent comprehensive properties should be proper.
