Position: Products

Code: Cr20Ni80、Cr30Ni70、Cr15Ni60、Cr20Ni35、Cr20Ni30

Material: Nickel-Chrome flat wire

Specifications: Thickness:0.04-0.80mm, width:0.4-6.0mm

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
