 Characteristic

HY I36 alloy 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°C and 200°C.
2.Good toughness and plastic

Metallurgical structure

HY I36 is the face centered cubic lattice structure

Corrosion resistance

HY I36 has corrosion resistance in the dry air of room temperature. In other harsh environments, such as the humid air, there may be corrosion (rust).

Applied field

HY I36 suit for need to apply ultra-low coefficient of heat expansion environment. Typical applications are as follows:
1.Liquefied gas production, storage and transport
2.The measurement and control instruments work temperature lower than 200°C, such as temperature regulating device
3.Metals and other materials use the screw connector bush
4.Bimetal and bimetallic temperature controller
5.Film framework
6.Shadow mask
