WebInvar is an alloy of nickel and iron. This alloy is also known generically as FeNi36 (64FeNi in the US). Invar is 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. WebInvar definition, a brand of iron alloy containing 35.5 percent nickel and having a very low coefficient of expansion at atmospheric temperatures. See more. sworn loyalty
