Super Invar® is an advanced version of the Invar alloy, where part of the nickel is replaced with cobalt in the iron-nickel base. This unique composition gives the alloy a nearly zero coefficient of thermal expansion at moderate temperatures.

The material can be machined using standard methods, similar to regular Invar. It produces long, thread-like chips that should be broken up during machining. Super Invar® is known for its rubbery texture and is not particularly hard. For best results, use a positive feed and low speeds. Thanks to its good ductility, the alloy can be easily shaped and formed using all conventional techniques, and it is also suitable for welding by standard methods. Cold forming is also possible due to its excellent ductility.

Super Invar® is ideal for use in precision measurement devices where dimensional stability and accuracy are critical despite temperature variations.
