Aluminium encyclopaedia

Weber’s ‘Aluminium Pocket Encyclopaedia’ contains the most important technical terms used in the aluminium industry and provides interesting information about aluminium, from A for Alloys through to Z for Zeppelin. It is intended to provide an introduction to the metal.

Economic efficiency

Like all materials, the use of aluminium is economical in those applications where the total costs of its use are the same or less than those for using other materials.

Electrical engineering

Overhead power lines, busbars and all types of cable are made from "conductor-grade aluminium". Although its conductivity is lower than that of copper, its density is significantly less thus making it more economical.


Aluminium is used as a conductor material in microchips, a reflector in CDs and the material for storage disks, cooling fins, housings, aerials and cables.


The extraction and processing of metallic raw materials results in the formation of gaseous, liquid and solid emissions. The aluminium industry is striving continuously to reduce these emissions.

Energy saving

As a great deal of energy is required for the extraction of primary aluminium, and this is coupled with high costs, the industry is continually striving to achieve energy savings in its own best interests. In applications appropriate for the use of alumin

Environmental protection

Measures to protect the environment are adopted along the whole value-added chain from bauxite mining through to recycling, and including aluminium extraction and processing.


Aluminium can be extracted from ore using several processes but only the Bayer"Hall"Héroult process is economical.


Widely used process for forcing aluminium through tool openings (dies) of the most varied range of cross-sections possible so that the strand takes on the same cross section, for example as a profile or tube.
