Super Invar is a special nickel–iron–cobalt alloy designed to achieve extremely low thermal expansion. Compared with standard Invar 36, Super Invar maintains higher stability in cryogenic and precision engineering applications. Due to its high nickel and cobalt content, the market price of Super Invar is much higher than common steels and even regular Invar alloys.
