Nickel-chromium Heating Wire

Product Name:nickel-chromium heating wire, band.
Product model:Cr20Ni80/ Cr30Ni70/ Cr15Ni60/ GH1140/Cr20Ni35/Cr20Ni30
Introduction:
Nickel-chromium alloy material is austenitic alloy, high temperature strength than the high-iron-chromium alloy material with high and stable resistance, corrosion resistance, good oxidation resistance of the surface, no distortion at high temperature, good viscosity, elongation than the iron-chromium alloy is 50%, processing prone to breaking, long after the plastic is better, do not become brittle after cooling, ease of repair after damage, regeneration of the alloy is good, is an industrial furnace, metallurgy, machinery, electrical appliances, aircraft, automotive, military and other industries producing heating elements and resistance elements preferred material.
