Abstract: The effects of the cold rolling deformation and the aging temperature and time on microhardness and electric conductivity of Cu-Ni-Si alloy were studied and the construction of its precipitate was investigated. The results show that cold rolling will accelerate the aging process and enhance aging effect. The alloy reaches excellent comprehensive property when aging for 1h at 500℃. The microhardness and electric conductivity of the alloy lean mainly on the quantity,particle size and dispersion degree of the precipitate.-
