Product Description

1.The picture of annealed nickel chrom heating wire

Annealed nickel chrom heating wire is characterized by high resistivity, stable mechanical properties. Nichrome alloys have higher elongation, better ductility and weldability.

2. Characteristics:

1) The highest working temperature up to 1200 degree.

2) Higher elongation

3) More stable mechanical properties

4) Better ductility and weldability.

3. Applications

Annealed nickel chrom heating wire is widely 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.
