Super Invar® is an enhanced version of the standard Invar alloy, where some of the nickel is replaced by cobalt in the iron-nickel composition. This adjustment gives the alloy an exceptionally low coefficient of thermal expansion at moderate temperatures.

The alloy can be machined using conventional techniques, similar to standard Invar. It tends to produce long, thread-like chips that need to be broken up, and is known for its “rubbery” texture rather than hardness. For best results, use a positive feed and low cutting speeds. Super Invar® is highly ductile, making it suitable for all common forming methods, and it is easily weldable by standard practices. Cold forming is also possible due to its excellent ductility.

This alloy is ideal for use in precision measuring equipment that demands high accuracy and dimensional stability under changing temperatures.
