Product Detail

Product Tags

Invar 36 is a special ultra-low coefficient of heat expansion of low-iron-nickel alloy. One of carbon and manganese element of control is very important. Cold deformation can reduce the coefficient of thermal expansion, in particular within the framework of the heat treatment temperature coefficient of thermal expansion will enable stabilization. Has the following characteristics:
1.Has very low coefficient of heat expansion between the temperature of -250℃ and 200℃.
2.Good toughness and plastic
