Invar

Invar

A nickel-iron alloy containing about 36% of nickel which, at ordinary temperatures, has the extremely small coefficient of expansion of about 1.5 millionth per degree Centigrade. Thus, Invar is practically completely non-expansible, and, as such, is made use of in the manufacture of clock pendulums, thermostats elements, internal combustion engine parts and the alike. It has a bright silvery appearance, and does not tarnish easily.
The name "invar" was originally coined as a contraction of the word "invariable."
