Electrical contact material
专利汇可以提供Electrical contact material专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain an electrical contact material provided with synthetically superior contact characteristics by adding specified amounts of Bi and Cd to Ag and carrying out internal oxidation.
CONSTITUTION: This electrical contact material is an internally oxidized electrical contact material consisting of, by weight, 2.5W10% Bi, 5W18% Cd and the balance Ag or further contg. 0.01W3% rare earth metallic boride and/or metallic carbide. By the composition the electrical contact material has sufficiently satisfactory welding resistance, consumption resistance and low contact resistance. A material having the composition is melted and atomized. The resulting powder is internally oxidized and worked by extrusion, drawing or other method to obtain a rivet-shaped electrical contact or the like with superior contact characteristics.
