Nickel Chromium Alloy Ni80cr20 Flat Wire Heat Element
Nickel Chromium Alloy Ni80cr20 Flat Wire Heat Element
Ni80Cr20 is a nickel-chromium alloy (NiCr alloy) It can produces dense well bonded coatings with excellent machineability, electrical conductivity and high temperature oxidation resistance up to 1800 degrees F (980 degrees C),and it hold a superior service life compared to Iron chromium alumium alloys.It exhibits exothermic heat during use
Application:
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%
