CERROMATRIX Alloy is a bismuth-base non-eutectic alloy that melts over the low temperature range of 218-440 F. Its low melting temperature and controlled-shrinkage characteristics make it a valuable tool of industry for such operations as anchoring punches in dies, repairing broken dies and filling blow holes in castings. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, heat treating, and machining. Filing Code: Bi-4.
