A name of this alloy originates from a word «invariant» which means «unchanged» and corresponds a truth because TCLE of Invar almost does not change in a temperature range -70º — +340ºC. This alloy relates to a group of precision alloys with a minimal TCLE in a range of temperatures -70º +340ºC, not higher than 4.5 — 5.5x10-6/C°) and is used in electrovacuum equipment. A precision alloy Invar 42 possesses unique physical, mechanical characteristics (magnetic, elastic, heating, electrical). It differs with a high accuracy of chemical composition, carefulness of manufacture and processing, an absence of residual elements. This category relates to a group of high-alloyed alloys. Such alloys are smelted on a basis of iron, nickel, copper, mangan, cobalt.

A usage of alloyed steels depends on work condition. Invar is a high-alloyed steel that is used in elastic details and is exploited at temperature to 300 °C. In comparison with analogous materials, this alloy possesses a high continuous operating period in specific conditions. It demonstrates an excellent resistance to a grain boundary attack and to corrosion cracking.
