Nickel Alloy Plates Invar 36 Used For Aircraft Controls And Radio & Electronic Devices

Nickel Alloy Plates Invar 36 Used For Aircraft controls , Optical & laser systems And Radio & Electronic Devices

1 . Description:

4J36 is a special low-expansion iron-nickel alloy with ultra-low expansion coefficient. The control of carbon and manganese is very important. Cold deformation can reduce the coefficient of thermal expansion, and heat treatment can stabilize the thermal expansion coefficient within a certain temperature range.

INVAR 36 nickel alloy plate (UNS K93603) is an austenitic nickel-iron alloy containing 36% nickel. It has an extremely low coefficient of thermal expansion from -418°F (-250°C) to 392°F (200°C). The alloy has good fatigue and mechanical properties at cryogenic temperatures. It exhibits moderately high strength along with good ductility and toughness. These properties along with good fabrication characteristics make INVAR 36 nickel alloy plate ideal for applications requiring precise dimensional stability.

INVAR 36 nickel alloy plate can be hot and cold worked, machined, and formed. Fabrication processes are similar to austenitic stainless steels. The alloy can be welded using filler wire with expansion rates similar to those of the base metal.

INVAR 36 nickel alloy plate resists corrosion in dry atmospheres at room temperature. In humid or moist atmospheres, corrosion can occur in the form of rust.
