Low Expansion Alloy Invar 36 Material Rod /Bar For Thermostats
1 . Descriptions:
Invar 36 is a nickel-iron alloy that contains 36% nickel and possesses a rate of thermal expansion approximately one-tenth that of carbon steel. Alloy 36 maintains nearly constant dimensions over the range of normal atmospheric temperatures, and has a low coefficient of expansion from cryogenic temperatures to about 500°F. This nickel iron alloy also retains good strength and toughness at cryogenic temperatures.
In addition, Invar 36® can be hot formed, cold formed or machined using processes similar to austenitic stainless steels.

5 . 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°C and 200°C.
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:
6 . Applications:
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°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
7.CRP components of the aviation industry temper Die
8.lower than -200°C the satellite and missile electronic control
unit framework
9.The auxiliary tube of the electromagnetic lens in the laser
control device
