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.

Flexible laminates

Aluminium foil made kink-resistant and stretchable for packaging by lacquering or by coating with plastics or paper.

Foamed aluminium

Very light aluminium material containing bubbles, used for floating bodies, thermally insulating and impact-absorbing elements as well as filters.


Thin aluminium less than 0.2 millimetres thick produced by rolling; it is impermeable to gases and light and is mainly used as packaging material for foodstuffs and medication.

Food packaging

Aluminium is widely used as a packaging material for foodstuffs. Compared with other materials, its main advantages are complete impermeability to gases, liquids and light as well as its very good processability.


Shaping of workpieces using processes such as extrusion, forging, rolling or drawing. In the case of aluminium, partly possible at room temperature.

Fused-salt electrolysis

Only process used to extract aluminium commercially: aluminium oxide is broken down into aluminium and oxygen using direct current.
