Invar 36 is an iron-nickel alloy with an extremely low thermal expansion coefficient and relatively low thermal conductivity. This confers exceptional dimensional stability, enabling it to remain distortion-free at specific temperatures. It is highly suitable for manufacturing high-precision components and can be used in environments sensitive to temperature fluctuations.
