Invar 36 Tubing
Invar 36 Tube, also known as Nickel Alloy 36 Tube, aka Invar 361, Pernifer 362, NILO 364, and Invar Steel Tubing. Invar 36 Tubing is a nickel-iron alloy noted for its uniquely low coefficient of thermal expansion & contains 36% nickel and possesses a rate of thermal expansion approximately one-tenth that of carbon steel.. Invar 36 Seamless Tube is magnetic at temperatures below its Curie point and non-magnetic at temperatures above. Invar 36 Seamless Tubing is the standard alloy for low expansivity up to 400 °F. This nickel iron alloy Invar Alloy 36 Tube also retains good strength and toughness at cryogenic temperatures. Invar Alloy 36 Tubing are became good choice in many industries because Invar 36 seamless tube exhibit a coefficient of thermal expansion (CTE) which is close to zero. This feature of Invar 36 coiled and straight length tubing has made UNS K93600 one of the most effective alloys for the manufacturing of precision instrumentation. Invar 36 High-Pressure Tube is generally thought of as the metal of choice for any type of low expansion application, because it has a very small CTE.
