为实现汽车零部件对压铸铝合金导电性、强度、成型性和低成本的需求，以 Al-Fe 系合金为基础，研究了 Fe含量对压铸铝合金导电率和机械性能的影响，进行了微观组织分析和高温性能稳定性验证，并探究了热处理工艺的影响。 结果表明， Al-(0.25%~3.0%)Fe-0.02%B( 质量分数 ) 合金具有良好的压铸成型性，添加 Fe 可显著提升合金的强度且不造成导电率的大幅下降， Fe 含量从 0.25% 增加到 3.0%( 质量分数 ) 后，抗拉强度增加 130% ，导电率仅下降 17% 。在高温工况下，材料导电率和抗拉强度仅略微下降，表现出较好的高温稳定性。 时效处理后导电率提升约 1.4%IACS ，强度提升约 7 MPa 。 Al-Fe 系合金是适合开发兼具高导电、中强度、低成本、可压铸等特点的合金体系。

In response to the current technical problem of balancing electrical conductivity, mechanical properties, cost and die-casting fluidity of cast aluminum alloys, a novel Al-Fe alloy was investigated with gradient Fe contents to maximize mechanical properties while maintaining a high electrical conductivity. The microstructure, high-temperature stability and different heat treatment processes were also examined. The results suggest that Al-(0.25%~3.0%)Fe-0.02%B(mass fraction) alloys exhibit good casting fluidity. Adding Fe could significantly improve the mechanical properties but slightly lower the electrical conductivity, as the strength increases by 130%, but the electrical conductivity decreases by 17% when the Fe content varies from 0.25% to 3.0% . The electrical conductivity and mechanical strength both slightly decrease in a high-temperature environment with decent stability. Aging treatment slightly improves both the electrical conductivity and strength by approximately 1.4%IACS and 7 MPa, respectively. The Al-Fe alloy should be a promising candidate for a high conductivity, middle strength, low-cost die-casting material.
