The controlled expansion nickel-iron alloy, Invar plays a crucial role in many domestic and office appliances. Invar is the forerunner of a family of nickel-iron alloys which form the essential part of bimetals and thermostats. It is used today in vast numbers of household appliances, from electric irons and toasters to gas cookers, fire safety cutoffs and so on.
In the office, computer terminals and TV screens make extensive use of Invar alloy and other Ni-Fe alloys for shadow masks, frames, and cathode ray tube gun parts. Other than these uses of these special alloys they are also found in industry for advanced electronic components, filters in mobile phone networks and even as tank membranes for massive liquefied natural gas transport ships.
Invar material is a 36% nickel iron alloy which has the lowest thermal expansion among all metals and alloys in the range from room temperature up to approximately 230°C. The Invar alloy material is ductile and easily weldable, and machinability is similar to austenitic stainless steel. It does not suffer from stress corrosion cracking. The mean coefficient of thermal expansion (CTE) of Invar products from 20-100°C is less than 1.3 x 10-6°C-1.
