Invar 42 - UNS K94200 Bar

Invar 42® Bar is a nickel iron alloy that is used for controlled expansion and magnetic applications. Invar 42® Bar can be hot and cold formed, machined by processes similar to those used for austenitic stainless steels. The alloy is available in the following forms: Invar 36, Invar 42, Invar 48, Invar K, and Invar 77.

Carey Alloys is one of the largest exporter, manufacturer and supplier of Invar 42 Round Bars in India. Invar 42 Rods are used in several applications such as for the glass-to-metal seals in electronic tubes, transformer and capacitor bushings, automotive and industrial lamps, and other ceramic-to-metal and glass-to-metal applications. It may as well be used by means of hard glasses if a thin edged tubular seal is being used.

These Invar 42 alloy bars are a 41 percent nickel-iron controlled expansion alloy that has been used in an extensive range of glass-to-metal sealing functions. Also known as UNS K94200 Round Bars, our Invar 42 Bars are accessible to our valuable customers in different range of diameters, wall thicknesses and sizes in customized form and also at quite affordable rates.
