CERROBASE Alloy is a bismuth-lead eutectic alloy that melts at 255 F (124 C). It is characterized by initial shrinkage followed by slow growth. Its low melting temperature and/or growth-shrinkage characteristics make it a useful industrial material. Among many applications, it is used for (1) anchoring inserts in wood, metal or plastics, (2) drop-hammer dies, (3) duplicate patterns in pottery and foundry, and (4) liquid metal bath for heat treating. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, forming, heat treating, and machining.
