Abstract

Bismuth-21In-18Pb-12Sn is a bismuth-base eurectic alloy that melts at 136 F (57.8 C). It is widely used in industry because of is low melting temperature and its controlled-shrinkage characteristics. It provides the scientist, engineer and technician with an easily castable material that is ready for use soon after it freezes. The alloy can be recovered easily and recycled into new uses any number of times. Among its many applications are (1) Anchoring parts such as jet blades for machining, testing and inspection, (2) In the foundry for fusible cores in compound corse and (3) Low-melting solder. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, heat treating, machining, and joining. Filing Code: Bi-35. Producer or source: Producers of low-melting alloys.
