China Stranded Nichrome Wire Nichrome Wire 8020 Stranded Wire 2017, Find details about China Nichrome Strip, Nichrome Wires from Stranded Nichrome Wire Nichrome Wire 8020 Stranded Wire 2017
The Nickel-Chrome and Nickel-ChromeIron alloy wires are widely used as the high
resistance alloy for electrical heating and wire-wound reistors in metallurgical industry,
chemical industry and electrical industry,etc.This alloy wire has higher electrical resistance
coefficient, good anti-oxidation and anti-corrosion performance, and it also has good mechanical
workability and weldability, with a high strength at high temperature.
