Aluminum

Aluminum can be used both pure and in alloys. It is a metal with low density, good malleability and electrical conductivity.

Aluminum is widely used across various industries, especially in electrical engineering, mechanical engineering, computer technology, construction, but it is also commonly found in households.

We supply aluminum in the form of bars (round, flat, square, hexagonal, hollow), tubes, or sheets. We cut semi-finished products into precise pre-final dimensions using band saws.

Below you will find a selection of the most common material grades we work with. Note for mechanical properties tables: values may vary depending on the manufacturing process and profile – more precise information for a specific semi-finished product is available on request.

If you are interested in another grade or alloy, do not hesitate to contact us.
