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
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.
