Product Description

 

1.The picture of electrical heating wire Kanthal A-1 .

Kanthal A-1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2550°F). The alloy is characterized by high resistivity and very good oxidation resistance.

Typical applications for Kanthal A-1 are electrical heating elements in high-temperature furnaces for heat treatment, ceramics, glass, steel, and electronics industries.

2.Characteristics:

1) The highest working temperature up to 1400 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

  Electrical heating wire Kanthal A-1 is widely used in heat treatment equipment, auto parts,  

  and steel manufacturing,aluminum industry, metallurgical equipment, petrochemical equipment,

 glass machinery, ceramic machinery,food machinery, pharmaceutical machinery, power engineering industry,  and residential appliances.
