Aluminium alloys

The Kanthal program includes aluminium in three different conditions - bare aluminium, coated aluminium and anodized aluminium. The aluminium wire is used primarily as electrical conductors due to its inherent ability to rapidly dissipate heat and resist corrosion as well as its reduction in weight over other alloys.

Kanthal aluminium wire is widely used for hard disk drive coils, audio speaker coils with heat resistant enamels and high strength bond coats.
