Ni90Cr10 is an austenitic nickel-chromium alloy (NiCr alloy) for use at temperatures up to 1200°C (2190°F). The alloy is characterized by high resistivity, good oxidation resistance and very good form stability. It has good ductility after use and excellent weldability.
Ni90Cr10 is used for electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
Due to extremely good adhesion properties of the surface oxide, Ni90C10 offers superior service life compared to competitive nickel-chromium alloys.

CHROMEL vs ALUMEL is used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum limited to short time periods. Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures.Chromel: Chromel is an alloy of an estimated 90% nickel and 10% chromium. It is used on the fabrication of the positive conductors of ANSI Type E and Type K thermocouples, devices for measuring temperature consisting of two different conductors.
