About Alloy
Invar 42 (alloy 42, Nilo 42) / 1.3917 / UNS K94100 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.
