Alloy36 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.

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

Has good plasticity and toughness.

    INVAR®36 Application Area
• Production, storage and transportation of liquefied petroleum gas
• Measuring and control instruments whose working temperature is lower than +200℃, such as temperature regulating devices
• Screw connector bushing between metal and other materials
• Bimetal and temperature control bimetal
• CRP parts tempering mold for the aviation industry
