简要介绍了挤压铸造的工艺特点，对近年来铝合金在挤压铸造方面的研究现状及成果作了总结说明，目前采用挤压铸造工艺制备的铝合金中Al-Zn系合金的力学性能要高于Al-Mg系、Al-Si系、Al-Cu系合金，但其耐腐蚀性能要低于这三种合金。%This paper described the technological characteristics of the extrusion casting, summarized the research status and results of aluminum alloys in extrusion casting in recent years. The mechanical performance of Al-Zn alloy in current extrusion casting preparation is better than Al-Mg alloy, Al-Si alloy and Al-Cu alloy, but its corrosion resistance is lower than the three alloys.
