Low Expansion Alloy 4J36 Precision Alloy Invar 36Н / Fe-Ni36 Rod for Radio Industry

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.

Application: Require dimensionally stable variety of instruments, instrument parts; Bimetallic passive layer

Feature: 4J36 is a typical low expansion alloy; Long-term use by the aviation factory, stable performance. Mainly for the manufacture in the temperature range approximately constant element sizes
