Characteristic:
36 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℃ and 200℃.
2.Good toughness and plastic
Metallurgical structure
Invar 36 is the face centered cubic lattice structure
Corrosion resistance
Invar 36 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:
Invar 36 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℃, 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
7.CRP components of the aviation industry temper Die
8.lower than -200℃ the satellite and missile electronic control unit framework
9.The auxiliary tube of the electromagnetic lens in the laser control device
