Description
1) A soft metal alloy containing over 50% Tin. White metal originally contained tin (92%) and Antimony (8%), with small amounts of Lead or Copper. This mixture has a melting point of 246 C. The term is now used for any low melting alloy that contains tin with lead, or antimony. Examples are Babbitt metal, Pewter, and Britannia metal. White metal is used for bearings and in the casting of costume jewelry.
2) Name for iron arsenosulfide commonly used prior to the 1800s when chemical compound names were standardized (Schur, 1985).
3) An intermediate product (Copper sulfide) obtained during the conversion of copper matte to blister copper.
Synonyms and Related Terms
1) anti-friction metal; Babbitt metal; Britannia metal 2) iron arsenosulfide 3) copper sulfide; métal blanc (Fr.)
