摘　　要：结合高强度压铸铝合金试棒的力学性能测试及金相分析，研究铜铁等元素对压铸铝合金的组织和性能的影响。发现提高铜的加入量，对合金的强化有别于常规成型工艺，而且铜还可中和铁的有害作用，铁的含量控制适当，既不致影响合金的组织和性能，又可防止粘模。Combining the mechanical property test of the sample of the high strength die casting alloy and metallurgic analysis,the effects of copper and iron on the organization and mechanical properties of the die casting alloy are researched.It has been discovered that increased Cu weight fraction to the alloy streng-thening is different from nomal forming technology,and Cu can neutralize the detrilnental effects of Fe on the alloy.If the Pe content is controlled appropriately,it will not affect the organization and mechanical properties of the alloy,and prevent the alloy from pasting on the die mould.
