Lork Group high-quality Invar 36 (UNS K93603) is a nickel-iron, low expansion alloy that contains 36% nickel ,This nickel iron alloy is tough, versatile and retains good strength at cryogenic temperatures.

Lork Group high-quality Invar 36 (UNS K93603) is a nickel-iron, low expansion alloy that contains 36% nickel and possesses a rate of thermal expansion approximately one-tenth that of carbon steel.

Invar 36 maintains nearly constant dimensions over the range of normal atmospheric temperatures, and has a low coefficient of expansion from cryogenic temperatures to about 500°F. This nickel iron alloy is tough, versatile and retains good strength at cryogenic temperatures.

Invar 36 (also known as Nilo, Nilvar, Permalloy D, FeNi36, and 64FeNi) is an nickel-iron alloy notable for its extremely low thermal expansion. Primary uses for Invar include laser and cryogenic components, tooling, dies, and any other application requiring high dimensional stability.
