Abstract

1351215 Contact material SIEMENS A G 19 April 1971 [26 March 1970] 25464/71 Heading C7A [Also in Division H1] A compacted powder which is diffused into a vacuum switch contact of highly degasified copper consists of a mixture of 10g of silver, 15g of copper and 1g of bismuth. At a diffusion temperature of 1000‹ C there is developed a molten phase which form an equilibrium of 10g of silver and about 40g of copper with the bizmuth uniformly distributed.
