How aluminium is produced

Aluminium is an excellent material with unique, specific characteristics: light, corrosion-resistant and ultra-durable. The ultimate combination of benefits, making aluminium perfect for your window and door profiles. But how is aluminium actually produced? Discover the aluminium production process with us and learn about the unique characteristics of this versatile material.

The journey of aluminium starts with bauxite, an ore with a high concentration of aluminium oxide. In a first step, the ore is removed from the ground surface, then grained and refined to obtain aluminium oxide. After the chemical (Bayer) process, an electrolytic (Hall-Heroult) process follows in which the aluminium oxide is melted to release pure aluminium. Afterwards the fluent material is casted into ingots. The result: primary aluminium.
