The Effect of aging treatment on mechanical properties, electrical conductivity and microstructure of the alloy Cu Zn Cr were studied. The results show that the aging process of the alloy after solution treatment and cold deformation was controlled by both precipitation of the supersaturated solid solution and recrystallization of the matrix. The high strength comes from strain hardening and precipitation strengthening of the precipitated chromium particles. And the high electroconductivity is mainly due to the composition close to Cu Zn solid solution matrix after precipitation.
