Details :

                                                  Nickel chrome electrical alloy heating wire                                                                                  

 

Nickel chrome alloy wire     are characterized by high resistivity, good oxidation resistance and very good form stability. They have good ductility after using and excellent weldability.

 

Nickel chrome alloy wire     are used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
