Ni-Cr heating wire

Code: Cr20Ni80, Cr15Ni60, Cr20Ni35, Cr20Ni30

Category: Ni-Cr heating wire

Specifications: f0.035mm~f9.0mm

Features: Nickel-chromium, nickel, ferrochrome alloy wire with electric high temperature oxidation resistance, high strength, not soften and a series of advantages. When used in a long time, the same type and the permanent elongation is very small, which is more Cr20Ni80 alloy with excellent comprehensive properties, is to produce high-quality varieties of choice for electric components. The products are widely used in industrial furnace, metallurgy, machinery, household appliances and other industries producing heating elements and resistance elements
