Seamless Invar Nickel Iron Alloy TubeSuper Invar Alloy Seamless Invar Nickel Iron Alloy Tube

Nickel iron alloy invar tube is an iron-nickel-cobalt alloy consisting of 32% nickel, 5% cobalt and a balance of iron. Super inar alloy has the least thermal expansion at room temperature (half that of inar 36 alloy) and has lower thermal expansion properties than inar 36 alloy in the temperature range of 67/203°F (-55/95°C).
