Precision Alloy Invar 36 Rod FeNi36 4J36 Alloy Bar 3.0 - 50.0mm
Diameter
Description
Invar 36, also known as FeNi36, is iron-nickel alloys have low
coefficients of expansion over only a rather narrow range of
temperature. It has a low coefficient of expansion from cryogenic
temperatures to about 260℃. In the dry air at home temperature,
invar 36 has good resistance to corrosion. But in moist air, it may
go corrosion.
Invar 36 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℃, aperture mask, unit frameworks working below
-200℃ and so on.
