Product Description

Nickel Chromium Wire

Nickel-Chrome & Nickel-Chrome-Iron alloy wire
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.
