36 Nickel Iron Invar Bar Description
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.
36 Nickel Iron Invar Bar is suitable for the applications who require low coefficient of
expansion, such as production, storage and transportation of liquid
gas, temperature regulation devices working below 200°C, aperture
mask, unit frameworks working below -200°C and so on.
