Product Description

Invar alloy (Invar 36) 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.


Chemical composition
Ni=35.0~37.0, Fe=Remainder, Mo≤0.50, C≤0.1, Cu≤0.5, Mn≤0.60, Si≤0.35, P≤0.025, S≤0.025, Cr≤0.5



  • Low expansion rate up to 500°F
  • Readily weldable



  • Cathode Ray Tubes
  • Telecommunications, aeronautical and aerospace engineering
  • Cryogenic engineering (liquefied natural gas tankers)
  • Where requires either high dimensional stability with variation in temperature, or expansion characteristics matched with those of other materials, such as glass, ceramics, or composites.
