VDM® Alloy 36 is an austenitic binary iron-nickel alloy with a particularly low coefficient of expansion. Control of carbon and manganese contents as well as impurities is important.
VDM® Alloy 36 (1.3912/K93600) is ferromagnetic at temperatures below the Curie temperature and non-magnetic at temperatures above. Cold deformation reduces the thermal expansion. A 3-step ageing treatment stabilizes the coefficient of expansion within a selected temperature range.
Typical applications are:
