        Code: Cr20Ni80、Cr15Ni60、Cr20Ni35、Cr20Ni30
        Material: Nickel-Chrome, Nickel-Chrome-Fe wire
        Specifications: φ0.035mm~φ9.0mm
        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
