- FeNi36 alloy W. Nr.1.3912 invar 36 seamless pipe / tube
Precision alloy Invar 36, also known as FeNi36, is a nickel-iron, low-expansion alloy containing 36% nickel. Precision alloy invar 36 has a low coefficient of expansion from cryogenic temperatures to about 260°C. In the dry air at home temperature, precision alloy invar 36 has good resistance to corrosion. But precision ally invar 36 moist air, it may go corrosion.
Precision alloy 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°C, aperture mask, unit frameworks working below -200°C and so on.
Product sizes are:
Invar Wire: 0.1mm-9mm
Invar Bar: 11mm-200mm
Invar Strip: 0.1mm-4.0mm*10mm-290mm
