For those who are not yet very familiar with the various materials we offer, we would like to provide a brief overview of the properties of the alloys on offer.
Information without guarantee for completeness/correctness
In its pure form, aluminum is already a versatile material. It is easy to form, has a visually appealing surface and is comparatively light.
As an alloy together with other elements, the areas of application can be expanded in many ways. Magnesium (Mg), silicon (Si), copper (Cu), manganese (Mn) and zinc (Zn) are the most important alloying elements.

A European standard groups the different alloys into groups/classes with similar properties using a 4-digit number combination.
1000 Group - Pure aluminum at least 99% Al - not hardenable, best physical property in terms of electrical thermal conductivity, best formable
Use : Aluminum foil, chemical tanks and pipes
2000 Group - Copper - hardenable - has a high strength and is difficult to cold form, is mainly used for machining, moderately corrosion-resistant and can be welded to a limited extent
Use : Aircraft construction and aerospace
3000 Group - Manganese has only a slightly higher strength than pure aluminum, is not hardenable
Use : Cooking pots, vehicle coolers and power plant construction
4000 Group - Silicon hardenable and non-hardenable alloys, lowers the melting point
Use: ideal for welding and soldering additives
5000 Group - Magnesium , non-hardenable, are very often used for cold forming of sheet metal and offer a special strength
Use: Shipbuilding, transport, pressure vessels, bridges and buildings as AA5024 (AlMgSc) also for aviation use
6000 group - Magnesium, silicon are hardenable and have a high strength. The 7000 series contain copper and have the highest strength values
Use: mainly as extruded profiles
7000 Group - Zinc is hardenable and has a high strength. The 7000s contain copper and have the highest strength values
