The 50 Nickel-Iron Alloy is recommended for glass-to-metal seals. It is used with such glasses as Types 0120 and 9010 that have higher than normal thermal expansion and with certain ceramics. It is used in a number of applications where expansion must be almost linear to 1000 F. The 50 Nickel-Iron Alloy has relatively good mechanical properties; in fact, at room temperature it has a tensile strength of 80,000 psi and an elongation of 35%. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-276. Producer or source: Mills that produce iron-nickel alloys.
