Elinvar

Japanese: エリンバー
Elinvar
An alloy used for instrument springs, etc. Also known as Elinvar. It is mainly composed of iron, with 36% nickel, 12% chromium, and 1-2% manganese. It is named after "elastic invariable." It has the characteristic that the temperature coefficient of Young's modulus is almost constant near room temperature (Elinvar effect), and the thermal expansion coefficient is also very small. CE Guillaume of France discovered the composition and properties of this alloy while researching Invar.
