INDALLOY No. 7 is a solder (50% indium-50% lead) that drastically reduces gold scavenging when used to solder components to gold-coated substrates in place of conventional (63% tin-37% lead) solder. Thus it has had obvious applications in the hybrid microelectronics industry. This datasheet provides information on composition, physical properties, microstructure, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: In-2. Producer or source: Indium Corporation of America.

It can be recovered easily and recycled into new uses any number of times. Among its many applications are proof-casting, liquid seals for heat-treating furnaces, non-shrinking patterns and dental models. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, forming, heat treating, and machining. Filing Code: Bi-18. Producer or source: Indium Corporation of America.

INDALLOY 217-440 is a bismuth-base alloy that can be melted easily. It is a non-eutectic alloy that melts through a temperature range of 217-440 F. Its low melting temperature and controlled-shrinkage characteristics make it a valuable tool of industry for such applications as anchoring non-moving parts in machinery, filling blow holes in castings, split jaw chucks and anchoring 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-22. Producer or source: Indium Corporation of America.

INDALLOY 158 is a bismuth-base, eutectic alloy that has a melting point of 158 F (70 C). It is an easily castable material that is ready for use as soon as it freezes. It can be recovered easily and recycled into new uses any number of times. Its low melting temperature and controlled-shrinkage characteristics make it of great use in industry for such applications as sprinkler and fire safety devices, support for bending pipe and tubing, anchoring aircraft parts for machining, and seals for annealing and nitriding furnaces. 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-27.

INDALLOY 160-190 is a bismth-base low-melting alloy that melts through th temperature range 160-190 F. It shrinks immediately upon solidification, grows back to zero in about one hour and then shows additional growth. This shrinkage-growth behavior makes it an ideal alloy for proof casting and precision measurement of internal dimensions. This alloy originally was developed for use by children for casting soldiers and other small objects. It performs best among the low-melting alloys for spraying in the spray forming of masks and molds and in metallizing. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, heat treating, machining, and joining.
