Introduction
Invar is a low expansion alloy consisting of 36% Nickel, balance
Iron. Invar Alloy exhibits extremely low expansion around ambient
temperatures, making Invar Alloy particularly useful in
applications where minimum thermal expansion and high dimensional
stability is required, such as in precision instruments like
optoelectronic devices, optical and laser benches, electronics, and
other kinds of scientific instruments.
Character
Low expansion rate up to 500°F
Readily weldable
Application
Cathode Ray Tubes
Other application areas, such as telecommunications, aeronautical
and aerospace engineering, cryogenic engineering (liquefied natural
gas tankers) etc., require either high dimensional stability with
variation in temperature, or expansion characteristics matched with
those of other materials, such as glass, ceramics, or composites.
