Invar, also known generically as FeNi36 (64FeNi in the US), is a nickel–iron alloy notable for its uniquely low coefficient of thermal expansion (CTE or α). The name Invar comes from the word invariable, referring to its relative lack of expansion or contraction with temperature changes. The discovery of the alloy … See more Like other nickel/iron compositions, Invar is a solid solution; that is, it is a single-phase alloy. In one commercial version it consists of approximately 36% nickel and 64% iron. The invar range was described by Westinghouse … See more Invar is used where high dimensional stability is required, such as precision instruments, clocks, seismic creep gauges, television shadow-mask frames, valves in engines and large … See more A detailed explanation of Invar's anomalously low CTE has proven elusive for physicists.

Webthe discovery of Invar, watchmakers struggled with even the best compensat-ed watches and chronometers because of the non-linear variation of the elasticity of the steel in the hair spring. Invar was the answer to this problem. Watches produced by the Invar Watch Company began appearing with the word “Invar” printed on the dial and stamped on WebInvar has poor heat conductivity, a low coefficient of expansion at temperatures below 300 oC, normal coefficient of expansion at higher temperatures, and an elastic modulus 79% of steel. These conditions promote internal strain and distortion. Note carefully the section on stress relief. We suggest a rapid air cool instead of a water quench
