Abstract: The influence of Zn content and residual strain on the relationship between resistivity and temperature of Cu-8%~13%Zn alloys was studied. The results showed the resistivity variation of studied CuZn alloys due to temperature elevated is independence to Zn content and residual strain. In the range of 0~150℃, the resistivity variation to temperature of studied CuZn alloys follows the relationship of ΔρΔt=0.0073×10-6Δt . And the extended applying of Matthissen rules on high concentration solid solution were farther discussed.
