NILO® Alloy 42

1.3917  /  UNS K94100

A binary nickel-iron alloy containing 42% nickel.  It has a low coefficient of thermal expansion (CTE) over the temperature range 20-300°C.  Due to this stable CTE it is widely used as tooling for the production of carbon-fibre composites for aerospace and autosport applications.  It is used for glass sealing applications in electronic components and vacuum devices, for thermostat rods and in thermostatic bimetallic strip.
