Word: Invar

Part of Speech: Noun

Definition: Invar is a special type of metal that is made by mixing iron and nickel. This metal is unique because it doesn’t change size much when the temperature changes. This property is called having a "low coefficient of thermal expansion." Because of this, invar is very useful in instruments that need to measure things accurately, like tuning forks and measuring tapes.
