| Abstract: | CuCr contact material has excellent mechanical and electrical properties and is widely used in vacuum switchgear. In this paper, the effects of Cr content on the breaking capacity, chopping current, high voltage withstanding and anti-weld property of CrCu contact material are reviewed. The function of other new alloy composition on its properties is also summarized. For the existing problems of CuCr contact material it is pointed out that strict control of the purity of raw materials and addition of new alloy are the main trend for development of high performance CuCr contact material. |
