摘　　要：概述了铝合金挤压铸造的优点,以及实现“以铸代锻”需要重视的三个方面:第一选择可热处理强化的高强铝合金;第二必须同零部件设计工程师密切沟通,不断优化铸件结构以利于挤压铸造工艺;第三必须有严格的铸造工艺控制,从不同方面减少挤压铸件的含气量。The merits of squeeze casting are summarized in this paper, and three important factors must be emphasized if the engineers want to use casting parts replacing forging parts. First, the high strength heat treatable aluminum alloy must be selected;second, continuously communicating with the parts designer and optimizing the structure of the parts must be done to ensure the parts are suitable for the squeeze casting process;third, strict casting process must be followed to minimize the gas content of the squeeze casting parts.
