Six-Sides Sawn Aluminium Cast Plates Impact-506 (EN AW 5083)

Universally applicable – the solution for medium-strength applications! Because of the specific in-house heat treatment, these products get a homogeneous microstructure over the entire ingot cross-section. This is an important distinctive feature of rolled plates. The strength of rolled plates decreases towards the ingot core. These medium-strength, six-sides sawn aluminium plates are characterised by excellent form stability, very good machinability and very good corrosion resistance. Therefore it is an excellent solution for mechanical engineering and mould-making.

Restricted process parameters in the products ensure a very high reproducibility over long production periods. Available in thicknesses up to 1,070 mm / 141.73 in.

Comprehensive range of both Metric and Imperial sizes are available to order.
