Sep 02, 2017 · While it took some time, it became apparent that the perfect mix of iron and nickel was 64% iron and 36% nickel. It was this particular mix of metals which gave the least amount of thermal expansion (the material is best known for its low coefficient of thermal expansion) and hey presto, the discovery of Invar. Invar Iron-Nickel Low expansion alloy properties and usesInvar basically belongs to a family of low expansion iron-nickel alloys, the popular members are:Invar consisting of 64 percent iron and 36 percent nickel called as Invar 36 or Nilo 36 SuperInvar consisting of 63 % iron, 32 % nickel, 5 % cobalt Kovar consisting of 54 % Iron, 29 % Nickel and 17 % cobalt.

Low-Expansion Alloys Properties and Selection Low-expansion alloys are various binary iron-nickel alloys and several ternary alloys of iron combined with nickel-chromium, nickel-cobalt or cobalt-chromium alloying and are used in applications such as geodetic tape, bimetal strip, glass
Alloy 36 is nickel-iron low-expansion super alloy, that is sold under the brand names Nickel Alloy 36, Invar 36® and Nilo® 36. One of the main reason people chose Alloy 36 is its specific capabilities under a unique set of temperature constraints. Alloy 36 retains good strength and toughness at cryogenic temperatures due to its  Nilo® 48 Glass To Metal Sealing Invar® 48 Alloy ManufacturerAbout Nilo 48 Invar 48. Nilo 48 (Ni 48%, Fe Bal%) is a low expansion Nickel-Iron alloy. The coefficient of thermal expansion of this metal is designed to suit the CTE of soft lead and soda lime glasses. High Inflection point. Its service temperature goes as high as up to 450oC or 840oF.
Super-Invar undergoes a phase change when cooled to under -50 C so it is not a good material of choice when exposure to such low temperatures is anticipated. On the other hand, standard Invar is much less stable over extended time (typical dimensional change 2 ppm/yr) than Super-Invar or several other low-expansion materials. Super High Resistance Nickel Invar - Buy Product on Super High Resistance Nickel Invar ,A low expansion alloy consisting of 32% Nickel, 4% Cobalt, and balance Iron. Super Invar Alloy exhibits minimum thermal expansion at room temperatures (one half of Invar Alloy), as well as thermal expansion properties less than that of Invar Alloy in the 67/203°F (-55/95°C) temperature range.

Invar (36% NI-Balance Iron) Alloy has been the metal of choice for low expansion applications for years. "Super-Invar" (31% NI-5% Co-Balance Iron) has found some favor because it has a near zero coefficient of thermal expansion over a limited temperature range. The useful range of "Super Invar" is limited between -32° to + 275°C because the material begins to transform
