Resistance & Controlled Expansion Alloys

NiCr, FeCrAl, CuNi & NILO® Alloys | Resistance & Controlled Expansion Materials | Precision Wire & Strip

Knight Precision Metals supplies specialist resistance and electrical alloys for applications requiring controlled electrical resistance, temperature stability and reliable performance in demanding environments.

Our range includes nickel-chromium resistance alloys NiCr 37/18, NiCr 60/16 and NiCr 80/20, alongside commercially pure Nickel 200 and 201, Nickel 212 and iron-chromium-aluminium (FeCrAl) ICA alloys.

We also supply an extensive range of copper-nickel resistance alloys, including CuNi2, CuNi6, CuNi10, CuNi23, CuNi30 and CuNi44, as well as NILO® controlled-expansion alloys including NILO® 36, 42, 48, 52 and NILO® K.

Available in precision wire and selected strip forms, these materials support applications including heating elements, control resistors, furnaces, thermocouples, heating cables, instrumentation, glass-to-metal sealing and specialist electrical components.

Our material expertise is backed by precision processing capabilities, enabling supply in customer-specific dimensions, tolerances and production-ready formats.

From prototype and development quantities to repeat production supply, we provide the material expertise, processing flexibility, traceability and global logistics required for specialist electrical applications.
