—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

NICKEL-CHROMIUM 80 (NiCr) wire alloys for use at temperatures up to1200°C 

 

NICKEL-CHROMIUM 80 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.

NICKEL-CHROMIUM 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, NICKEL-CHROMIUM 80 offers superior service life compared to competitive nickel-chromium alloys.
