36NiFe


Common Trade names: Nilo 36, Invar 36, Pernifer 6, Invar 6, Nilo6

Overview

36NiFe wire has negligible change in its dimensions over the higher temperature ranges up to 500°C. It retains its mechanical properties and hardness at cryogenic temperature ranges and used as a component in the bimetallic strip.
