Product Description

1.The picture of heat resisting wire .

Kanthal AF is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1300°C (2370°F). The alloy is characterized by excellent oxidation resistance and very good form stability resulting in long element life.

Kanthal AF is typically used in electrical heating elements in industrial furnaces and home appliances.

Example of applications in the appliance industry are in open mica elements for toasters, hair dryers, in meander shaped elements for fan heaters and as open coil elements on fibre insulating material in ceramic glass top heaters in ranges, in ceramic heaters for boiling plates, coils on molded ceramic fibre for cooking plates with ceramic hobs, in suspended coil elements for fan heaters, in suspended straight wire elements for radiators, convection heaters, in porcupine elements for hot air guns, radiators, tumble dryers.

2. Characteristics:

1) The highest working temperature up to 1300 degree.

2) Longer working life,and better technical properties

3) Higher surface load.

4) Higher resistivity.

5) Lower density.

6) Free from oxide debris

3. Applications

Heat resisting 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.
