Invar is a nickel-iron alloy best known for its very low thermal expansion coefficient, one of the lowest of all metals. It is also strong, tough, ductile, and used where high dimensional stability is required. Invar is magnetic in the temperature range in which exhibits the low expansion characteristics.
