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.
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.
