Kovar Alloy Tube Pipe is a nickel-iron, low-expansion alloy containing 28.5% 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.
Kovar Alloy Tube Pipe 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.
Precision alloy series: 1J33,3J01,3J9,4J29,4J32.4J33,Invar36,4J45.FeNi50.
Main applications: Magnetic shunt compensatory element In the electromagnetic loop and the permanent magnetic loop.
