Abstract:High-conductivity aluminum alloy has the advantages of low density, strong plasticity, and good electrical conductivity, and can play an important role in many fields. As humans continue to improve the performance requirements of highly conductive aluminum alloys, it is necessary to continue to improve the comprehensive properties of aluminum alloys. In this paper, through experimental analysis, different element contents are added to high-conductivity aluminum alloy, and the influence of different element contents on the properties of aluminum alloy is analyzed. The experimental results show that adding 0.2% of magnesium to the high-conductivity aluminum alloy can improve its mechanical properties and conductivity; adding 2% of copper to the high-conductivity aluminum alloy is beneficial to the overall performance of the alloy; 0.3% rare earth lanthanum is added to the highly conductive aluminum alloy, and the tensile strength of the alloy reaches the maximum.
