Abstract

By comparing nine groups of experiments, the influences of Mg, Si, Cu and Mn on the strength, plasticity and conductivity of 6005 alloy were researched. The results show that α-Al, Mg2Si, Si and β-AlFeSi are mainly present in the as-cast microstructure of 6005 aluminum alloy. The strength, plasticity and electrical conductivity of the 6005 aluminum alloy of 9 groups were compared and then select a good overall performance of an alloy composition, which is Al–0.53Mg–0.72Si–0.2Cu–0.28Mn–0.18Cr–0.05Ti (wt%). The tensile strength, yield strength, elongation, hardness and electrical conductivity of the extruded alloy are 310.9, 280.1 MPa, 11.95%, 102.3 HV and 47.2% IACS, respectively, after solid solution, air-cooling and 175 °C × 8 h aging.
