Invar Fe-Ni36 4J36 Low Expansion Iron Nickel Alloy 1.2 ppm°C Anti Corrosion 4J36 is a special low-expansion iron-nickel alloy with an ultra-low expansion coefficient. Among them, the control of carbon and manganese components is very important. Cold deformation can reduce the coefficient of thermal expansion, and heat treatment in a specific temperature range can stabilize the coefficient of thermal expansion. 4J36 is resistant to corrosion in dry air at room temperature. In
