What is INVAR® 36 Properties and Appearance?

Invar® 36 belongs with the low expansion alloys, with a thermal expansion 1/10th of carbon steel at temperatures up to 400° F. Invar® 36 alloy maintains its strength at cryogenic temperatures and has nearly constant dimensions from sub-zero temperatures to about 500° F. Because of its small coefficient of thermal expansion INVAR® 36 is generally thought of as a good choice for any type of low expansion application requiring high dimensional stability such as the manufacturing of precision instruments. INVAR® 36 can be hot and cold formed and is both readily machinable and weldable.
