Effects of aging time on the hardness and conductivity of Cu-Ni-Si-Mg alloy were studied. The subzero treatment of the alloy at different time was carried out after aging. The effects of subzero treatment on the hardness and electrical conductivity were studied. Effect of subzero treatment on the properties of the alloy was analyzed by observing alloy microstructure before and after subzero treatment. The results show that the subzero treatment has a significant influence on alloy strength and conductivity.
