Aluminium production

NACE v2.1 Code: C24.42

About aluminium production

NACE code 24.42 covers the industry of aluminium production, a critical component of the global manufacturing and construction sectors. Aluminium is a lightweight, durable, and highly versatile metal that is widely used in a variety of applications, from transportation and packaging to electronics and renewable energy. As a key material in the production of many essential goods, the aluminium industry plays a vital role in supporting economic growth and development worldwide.

Production process

The primary production technique for aluminium is the electrolytic smelting process, also known as the Hall-Héroult process. This involves the reduction of alumina (aluminium oxide) dissolved in a molten cryolite bath, using an electric current to separate the aluminium metal from the oxygen. The molten aluminium is then cast into ingots, billets, or other shapes for further processing or use.

Production inputs

The main inputs required for aluminium production include bauxite (the primary raw material), electricity (to power the smelting process), and various other materials such as carbon anodes, cryolite, and alumina. Specialized equipment, including electrolytic cells, casting machines, and rolling mills, are also essential for the production of aluminium.

Production outputs

The primary outputs of the aluminium production industry are various forms of aluminium metal, including ingots, sheets, bars, and extrusions. These aluminium products are then consumed by a wide range of other industries, such as 25.11 Manufacture of metal structures and parts of structures, 29.10 Manufacture of motor vehicles, and 27.32 Manufacture of other electronic and electric wires and cables.
