The group of aluminium alloys includes aluminium materials relevant for practical applications. They are created by alloying with other metals, mainly manganese, magnesium, copper, silicon, nickel and zinc. This product category includes, for example, engine parts, wheel rims and moulds.

The pure light metal aluminium has a dull, silver-grey appearance due to a thin oxide layer that forms very quickly when it comes into contact with air.
This product category includes, for example, bare profiles.

This product category includes items such as washbasins and washing machine drums.

Stainless steel is a colloquial term for rust- and acid-resistant steel.
Thanks to the good formability of stainless steel sheets, parts made of this material are becoming increasingly widespread in industry, in the home and in medical devices.

Copper salts are usually blue or green in colour. As a semi-precious metal, copper has similar properties to the elements silver and gold, which are in the same group. Copper is used for coins, power cables, jewellery, cutlery, fittings, boilers, precision parts, works of art, musical instruments, pipes and much more. On account of its very good electrical and thermal conductivity, copper is suitable for use as chemically pure copper for electrical cables, conductors and components, as well as for heat sinks. This product category includes, for example, new wires.

This includes, for example, old sheet metal and water pipes.

The most well-known copper alloys include the many types of brass, which all contain varying amounts of zinc and produce a wide range of colours with a typical gold-like shine. Bronze, an alloy of copper and tin, is also very well known. This product category includes, for example, taps and bearing bushes.
In diese Produktkategorie fallen zum Beispiel Armaturen und Lagerbuchsen.

Lead is a heavy metal that can be easily moulded and cast into any shape. This product category includes, for example, drain pipes and earthing cable sheathing.
In diese Produktkategorie fallen zum Beispiel Abflussrohre und Erdkabelummantelungen.

A bluish-white metal used, among other things, to galvanise iron and steel parts and for rain gutters. This product category includes zinc sheets and gutters, for example.
In diese Produktkategorie fallen zum Beispiel Zinkbleche und Dachrinnen.

A silvery-white, shiny and very soft heavy metal that can be scratched with a fingernail. It is notable for its low melting point and relatively high boiling temperature. This product category includes, for example, solder and alloying additives.
In diese Produktkategorie fallen zum Beispiel Lötzinn und Legierungszusatz.
