Super Invar 32-5 Round Bar/ Rod ,Nickel Iron alloy Rod
1. Invar 36 (FeNi36)
Invar 36, also known as FeNi36, is a nickel-iron, low-expansion alloy containing 36% nickel. It has a low coefficient of expansion from cryogenic temperatures to about 260°C. In the dry air at home temperature, invar 36 has good resistance to corrosion. But in moist air, it may go corrosion.
