摘　　要：高强度锌铝合金是一种优良的工程材料,本文主要对此系列中ZZnA127Cu2(后简称ZA—27)的组织、性能进行了研究,并围绕该合金在汽车零件上的应用,对压铸生产工艺进行了试验研究。同时,鉴于压铸生产的特点,尤其是采用铁坩埚工频感应炉来配制及保温合金,着重对成分的偏析及铁对合金的污染进行了一系列的试验,从而获得简单、可靠的工艺规范,以利于ZA—27在汽车行业的压铸生产中大量推广应用。In this paper, the stwdy of the structure and properties of ZZn A127Cu2 alloy (called ZA-27 alloy for short) is made. It is a excellent engineering material, belongs to the series of high strength zinc-aluminium alloy. The paper describes the die casting process of the ZA-27 alloy used for automotive parts, the composition segregation and the iron pollution in the alloy. Especially the paper describes the melting and holding processes of the alloy which are been done by working frequency induction furnace with iron crucible. As a result of the test, a simple and reliable technological process is obtained. It makes the ZA-27 alloy to be used widely in the die casting production of the automotive industry.
