Description of Chrome Nickel Heating Wire

Nickel-chromium and nickel-chromium-ferroelectric heating alloy wires have a series of advantages such as good high temperature oxidation resistance, high strength and no softening. It does not change shape and has small permanent elongation when used for a long time.  Cr20Ni80 alloy has excellent comprehensive characteristics and becomes the first choice for making high-quality electric heating elements.
