Abstract

The mechanical and electrical properties of $Cu-TiB_2$ composites prepared by hot extrusion and cold drawing according to the variation of $TiB_2$ contents and the size of $TiB_2$ particle have been studied. The experimental results showed that the electrical conductivity was decreased with increasing the $TiB_2$ content, and their tensile strength and hardness increased inversely. In the case of the same content of $TiB_2$ particle, the smaller $TiB_2$ particle, the higher their mechanical properties. The electrical conductivity of $Cu-TiB_2$ composites showed more than 70%IACS. Their yield strength and hardness were more than 120 MPa and HRB 60～70, respectively.
