Study on Effects of Cu Content on Properties of Al-Mg-Si Aluminum Alloy

摘要：

　　The effects of Cu element on properties of Al-Mg-Si aluminum alloy was studied,and the mechanism of Cu in influencing the property of the alloy was discussed.The results indicate that Cu element can weaken the conductivity property of alloy material,its thermal conductivity is improved with slow cooling.Cu element is sensitive to corrosive property of the alloy,it can cause corrosion resistance decreasing significantly,quenching heat treatment made corrosive property of the material deteriorative.Proper Cu element is helpful to microstructure refinement and the enhancement of strength,tensile strength of the material is increased 10 percent after solution treatment and ageing strengthening.
