Super Invar® is an enhanced version of the Invar alloy, where part of the nickel in the iron-nickel base is replaced with cobalt. This adjustment gives the material an extremely low coefficient of thermal expansion at moderate temperatures.

This alloy can be machined using standard techniques, similar to regular Invar. It produces long, stringy chips that need to be broken during processing. The material is known for its "rubbery" feel rather than hardness. Machining is best performed with a positive feed at low speeds. Thanks to its good ductility, Super Invar® can be shaped and formed using all common methods, including cold forming. The alloy is also weldable by traditional methods.

Super Invar® is ideal for use in precision measuring devices that demand exceptional dimensional stability and accuracy under varying temperatures.
