Tin-Bismuth 60-40 is a tin-base alloy that can be melted easily. It is a non-eutectic alloy and melts through the temperature range 281-338 F (138-170 C). It provides scientists, engineers and technicians with an easily castable material that is ready for use soon after it freezes; in addition, it can be recovered readily an recycled into new uses any number of times. Among its many uses are fusible mandrels for electroforming, low-temperature solder, holding parts for machining, dies for a wax patterns for investments casting and liquid scals for furnaces. 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: Sn-12. Producer or source: Low-melting alloy producers.
