Invar36 is a special low-expansion iron-nickel alloy with 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.

It has a very low coefficient of thermal expansion between -250°C and +200°C.Has good plasticity and toughness.

Invar36 application field

•Production, storage and transportation of liquefied gas 

•Measuring and controlling instruments whose working temperature is lower than +200℃, such as temperature regulating devices 

•Screw connector bushings between metal and other materials 

•Bimetal and temperature control bimetal

•CRP parts tempering mold for the aviation industry 

•Satellite and missile electronic control unit frame below -200℃ 

•Auxiliary tube in electromagnetic lens of laser control device
