its a small set of nickel iron alloys that are available (to machinists at least) in a few configurations dictated by their iron/nickel content.
with the addition of cobalt it becomes Kovar, a metal that is common for telescope use or joints where metal bonds to glass.
they're all fairly proprietary and expensive. I've used Invar a lot in the production of heated press platens.

- buildsjets 3y agoYes, it is a name, but no, is not THE name. Invar and Inconel are completely different alloys with completely different use cases. I have specified them both. In aerospace, Inconel 625 and 718 are used in high temperature structural and transport element applications in aircraft. Invar is never used in aircraft structure, but it is used to make tooling that needs to be invariant in size, especially composite layup mandrels that are cured in autoclave ovens.
