Invar Products

What is Invar?

Invar is a nickel-iron alloy, primarily Invar Composition of 64% iron and 36% nickel, known for its extremely low coefficient of thermal expansion. This unique property allows Invar to maintain its dimensions with minimal change when subjected to temperature fluctuations. The Invar alloy is highly stable over various temperatures, making it ideal for applications where precision and dimensional stability are critical. The standard specifications for Invar include ASTM F1684, ASME SB1684, and DIN 1.3912.

What is Invar used for?

Invar is extensively used in manufacturing components that require precise dimensional stability due to its minimal thermal expansion properties. Key applications include clock pendulums, seismic creep gauges, and shadow-mask frames for cathode-ray tubes. In the aerospace industry, Invar is utilized for satellite and space probe components, where maintaining minimal expansion under varying temperatures is crucial. Its reliability and stability also make it suitable for scientific instruments and electronic components, ensuring high precision and performance in demanding environments.

The DIN standard for Invar is 1.3912, further assuring its quality and suitability for demanding applications.
