Product Description
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.
