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 Mn to Ag and carrying out internal oxidation.
CONSTITUTION: This electrical contact material is an internally oxidized electrical contact material consisting of, by weight, 0.5W10% Bi, 1W7% Mn 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, compressed, and sintered, and by working the sintered body by extrusion, drawing or other method, a rivet-shaped electrical contact or the like with superior contact characteristics is obtd.
