Product Description
TKN66 is an austenitic nickel-chromium alloy with a maximum operating temperature of 1200°C. This alloy has a low nickel content and a low temperature coefficient of resistivity. It can be used to replace alloys with higher nickel content. If nickel-chromium 80/20 is used for metal sheathed tubular electric heating elements, it can achieve the same service life as nickel-chromium 80/20.

Ni80Cr20 is a nickel-chromium alloy (NiCr alloy) characterized by high resistivity, good oxidation resistance and very good form stability. It is suitable for use at temperatures up to 1200°C,and hold a superior service life compared to Iron chromium alumium alloys.
Typical applications for Ni80Cr20 are electric heating elements in home appliances,industrial furnaces and resistors(wirewound resistors,metal film resistors), flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
