The many uses of aluminium

Aluminium is one of the most important metallic materials, second to steel only, and it is to be found everywhere. It has excellent properties in terms of flexibility, corrosion resistance, conductivity, and weight, which make it indispensable. The strength of aluminium alloys and their comparatively low weight make this material so valuable for us. At 35%, the largest area of use is the construction of vehicles, ships, aeroplanes, and rail vehicles.

Aluminium as electric conductor

Aluminium features the fourth-highest conductivity (after silver, copper, and gold). Its properties are especially advantageous when weight is an issue. Aluminium cables are used to achieve considerable weight reductions in the construction of aeroplanes.

Recycling of aluminium

In 2014, approx. 108 million tonnes of aluminium were produced, of this 53 million tonnes were primary raw materials (Source: World Aluminium). The recycling of aluminium saves energy, reduces CO₂ emissions and conserves resources at the same time (Source: www.alu.ch). Europe exports about 515,000 tonnes of aluminium waste (Source: European Aluminium). At present, about 70% of the aluminium used in Austria comes from secondary raw materials (Source: World Resources Forum).

Reliability of aluminium supply through recycling

As the high future demand is already on the horizon and the countries of the European Union have only limited access to primary aluminium (bauxite), the European Raw Material Initiative (European Commission 2014) was launched to promote and extend recycling.
