Production and demand
The demand for aluminium is increasing year by year. Many applications and developments require a material that is lightweight but nevertheless strong – requirements that aluminium can fulfil optimally. In addition, it is an extremely versatile material.
Shaped aluminium castings
Shape casting is used to produce finished products and various casting processes are used (sand, pressure die or chill casting) depending on the product, the size of the production series and the dimensional accuracy required. The car industry is the most important customer group for shape-casting foundries. The production of shaped aluminium castings (pressure die, chill and sand castings) in 2018 totalled 1,020,000 tonnes. A year earlier, in 2017, 1,045,100 tonnes of shaped aluminium castings were produced. This represents a fall in production in 2018 of about 2.4 per cent.

Semi-finished aluminium products
Production of semi-finished products in Germany in 2018 totalled 2,46 million tonnes. This represents a sideways motion year-on-year. The portfolio of products are rolled products, extruded products, wires and forged parts. Semi-finished products is the most important section of the German aluminium industry in quantitive matters.
1,854,900 tonnes of rolled products were produced in Germany in 2018. This is a small decrease of only 0.3 % year-on-year. In addition, some 579,000 tonnes of extrusions were also produced in Germany in 2018 and this was about one per cent less than the previous year. The production of technical aluminium wires developed well and managed to increase 6.5 per cent to 19,700 tonnes.

Packaging for foodstuffs, medication and body-care products is subjected to the highest possible demands. Aluminium is a flexible, multifunctional and lightweight packaging material here. Aluminium packaging is also a material par excellence for the circular economy and can be recycled without any losses after use to conserve resources. Aluminium converting includes the production of aluminium foil (2018: 262,900 tonnes), the manufacture of tubes, cans and aerosol cans (2018: 42,200 tonnes) and the production of aluminium powder (2018: 35,000 tonnes).
