Invar 42® - UNS K94200Request Quotation
Common Trade Names: Invar 42®, Nilo 42®
Invar 42® is a nickel-iron alloy that contains 41% nickel and exhibits excellent controlled expansion qualities and is used primarily for controlled expansion and magnetic applications. Invar 42® is also highly effective in magnetic applications. It can be hot formed, cold formed or machined. Nilo 42 possesses many of the qualities of the other Invar nickel iron alloys. It is effective in extreme temperatures ranging from -32C to 275C.
Why Choose Invar 42®?
Nickel iron alloys are widely known and utilized because they exhibit a coefficient of thermal expansion (CTE) that is close to zero. This beneficial quality has made nilo 42 one of the most effective alloys for the manufacturing of precision instrumentation. Invar 42® is widely known as the metal of choice for numerous glass-to-metal sealing applications.
