INVAR 36
Is containing 36% nickel, such a widely used material, and CTE (Coefficient of thermal expansion) is near to zero. Between the range of temperature, -250℃ to 200℃, this alloy‘s coefficient of expansion is about one tenth of carbon steel. This alloy also keep great strength and toughness in low temperature that is suitable for application in low expansion and low temperature. It is used for medical instrument, electronic engineering, manufactured components in aerospace, 3C and numerous component in low temperature.
