Introduction:

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.

Feature:

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. Main characteristics of Ni-Cr and Ni-Cr-Fe electric heating alloys
