NiCr Nichrome Fecral Alloy Alchrome Electric Heating Elements for
Industry Furnace
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.
