ISO 15608 Material Group 48:
Nickel-Iron-Cobalt alloys (Ni-Fe-Co-Cr-Mo-Cu) with 31 < Ni ≥ 45 % and Fe ≥ 20 %
Invar 36 alloy is a free machining 36% nickel iron alloy possessing a rate of thermal expansion approximately one-tenth that carbon steel at temperatures -150 °C up to 204 °C. It has a low coefficient of thermal expansion, making it useful for applications where dimensional stability is required. It is also known for its high strength and corrosion resistance.
