4j36 Uns K93600 Invar 36 Precision Expansion Alloy Strip/Coil/Foil with High Quality
INVAR 36 is a nickel-iron, low expansion alloy containing 36% nickel. It 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. The alloy also retains good strength and toughness at cryogenic temperatures.
INVAR 36 can be hot and cold formed and machined using processes similar to austenitic stainless steels. INVAR 36 is weldable using Filler Metal CF36 which is available in bare wire for both the GTAW and GMAW process.

| Basic performance | It is divided into low-expansion alloy and fixed-expansion alloy, the latter is also known as sealing alloy.Expansion alloy besides has the specific thermal expansion coefficient, according to the different USES also requires a good sealing property, weldability and corrosion resistance, machinability and cutting, and in the use of expansion characteristics caused by the temperature range there is no obvious change of phase transformation, its product is commonly bar, sheet, strip, wire and tube and so on. |
| Expansion alloy applications | It is widely used in glass, metal and ceramic sealing in avionics and instruments, electric vacuum industry and other electronic devices, electric light source and other fields. |
