Ni80Cr20 is a nickel-chromium alloy (NiCr alloy)
characterized by high resistivity, good oxidation resistanceand 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.
