China NiCr Alloy A resistance Alloy Strip Nichrome 8020 NiCr8020 Strip for Resistor Manufacture and Factory

NiCr Alloy A resistance Alloy Strip Nichrome 8020 NiCr8020 Strip for Resistor

Short Description:

Cr20Ni80 has excellent comprehensive properties. High-quality heating elements will choose Cr20Ni80. Cr20Ni80 has the advantages of good oxygen resistance, high strength, non-magnetic, high emissivity, good corrosion resistance, no softening, no deformation, and low permanent elongation. 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 Cr10Ni90 alloy with excellent comprehensive properties, is to produce high-quality varieties of choice for electric components.
