Cast Machined Aluminium Plates Impact-500 (EN AW 5083)

Characterised by excellent form stability, very good machinability, extremely low residual stresses and high strengths. The very fine-grained and homogeneous microstructure has almost no microporosity. Our aluminium cast machined plate is an ideal solution for precision parts with high demands. It has good form stability with extremely low residual stresses.

It is two sides precision machined and PVC Centered on both sides. The excellent flatness and thickness tolerance allows the shortest production times in areas such as mechanical engineering, gauge production and the construction of jigs and fixtures in all kinds of capital goods industries. This aluminium cast machined plate has been belt-sanded on both surfaces in the longitudinal direction, to receive a neutral surface, thus eliminating any milling marks.
