NiCr 80:20 – Industrial furnaces (upto 1200°C), electric cooking
equipment, precision resistors.
NiCr 70:30 – Industrial furnaces (upto 1250°C) with alternating
oxidizing/reducing atmosphere, precision resistors.
NiCr 60:15 – Industrial furnaces (upto 1150°C), electrically heated
equipment, high-resistance and potentiometer resistors.
NiCr 40:20 – Domestic heating appliances (upto 1100°C), furnaces in
carburising or semi-reducing atmosphere.
NiCr 30:20/ NiCr 20:25 – Industrial furnaces (upto 1100°C), heating
elements of cooking equipment.
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.
