Bismuth-28.5Pb-14.5Sn-9Sb is a bismuth-base non-eutectic alloy that melts over the low-temperature range of 218-440 F. Its controlled-shrinkage characteristics and low melting temperature make it a valuable industrial tool. It was developed and used originally for making punching dies to produce transformer laminations from silicon sheet steel. Now its many uses include filling blow holes in castings, anchoring dies and non-machinery parts, fixtures, jigs and hold-down bolts in concrete floors. 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-30. Producer or source: Producers of low-melting alloys.
