Abstract

1438044 Internally oxidized silver alloy CHUGAI DENKI KOGYO KK 14 March 1974 [22 March 1973 20 July 1973] 11348/74 Heading C7A An alloy comprising In 6-12% and Sn 0.5-5%, the balance being Ag is formed into a desired shape and internally oxidized to produce an electrical contact material. When the Sn content is over 2.5% there is added to the alloy less than 0.5% of an iron group metal (i.e. Co Fe or Ni) although this addition may be made for other Sn contents.
