Abstract

538,459. Alloys. JOHNSON, MATTHEY & CO., Ltd. April 1, 1940, No. 5872. Convention date, June 2, 1939. [Class 82 (i)] Electric contacts are made of silver alloys containing 0À05-15 per cent. of magnesium and 0À5-25 per cent. of zinc, with or without up to a total of 5 per cent. of copper, nickel, cobalt, iron, or manganese ; or contacts may be made from compositions wherein such alloys are used as bonding material added to finely divided iron, nickel, or cobalt. Specification 267,263, [CLass 82 (i)], is referred to.
