Product Description

Low Price Wholesale Nichrome 80 / 20 Cr20Ni80 Resistance Wire for Heating Element

NiCr Series

The Cr20Ni80 resistance wire is composed of nickel-chromium alloy, which has high resistivity, good oxidation resistance and very stability. The maximum applicable temperature is up to 1200 degrees, and it has a longer service life than iron, chromium and aluminum.The alloy is widely used in household components, industrial furnaces and various resistance components, such as wirewound resistors, sheet metal resistors, hair dryers, electric furnaces, iron smelting, ovens, and even electronic cigarettes.

Nickel-chromium, nickel, ferrochrome alloy resistance 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.
