Product Description


The Nickel-Chrome and Nickel-Chrome-Iron alloy wires are widely used as the high resistance alloy for electrical heating and wire-wound resistors 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.
