The above parameters are based on Chinese National Standard GB/T1234-2012. The tolerance of resistance per meter: 0.03-0.06mm is ±10%; 0.07-0.12mm is ±8%; 0.13-0.17mm is ±7%; 0.18-0.32mm is ±6%; A wire diameter above 0.32mm is ±5%. We provide nickel-chromium alloy products in various shapes, such as wires, ribbons, and rods. Other alloys like Cr20Ni80, Cr30Ni70 and Cr20Ni35/Cr20Ni30 are also available upon request.
