Resistance nichrome Alloy Wire Cr20Ni80 Cr30Ni70 Cr15Ni60 Cr20Ni35 Cr20Ni35 Cr20Ni30 NiCr 8020 Nichrome Wire


NiCr Series
- 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.
