INDALLOY 147 is a bismuth-base controlled-shrinkage alloy with a non-eutectic structure. It melts over the narrow, low-temperature range of 142-149 F (61-65 C). Indalloy 147 provides engineers and technicians with an easily castable material that is ready for use as soon as it freezes. It is highly suitable in industry for such uses as anchoring parts for machining and support for bending tubing and extrusions. 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-31.
