Cr80Ni20 nichrome tube Nickel alloy tube pure nickel tube Resistohm
80 tube 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.Normal composition%
