Zhang Yu-jia，Li Guo-qiang，Teng Bao-wen

[Abstract]The core component of vacuum circuit breaker is vacuum arc extinguishing chamber， which needs good breaking and arc extinguishing ability. Therefore， the internal contact material must have excellent performance of high strength and high conductivity. In this paper， the microstructure and properties of CuCrZrMg alloy contact material are studied. The microstructure and properties of the contact material are studied by optimizing the heat treatment and cold processing technology， and a preparation and processing technology that can improve the properties of the contact material is proposed.
