ACP 6000

Low inherent internal stress for high dimensional stability during extreme machining.

ACP 6000 is an aluminium precision cast plate that is precision-milled on both sides and has a comparatively high abrasion resistance. It is also characterised by low stress and high dimensional stability, even with complicated machining. To protect the precision-milled surfaces, all plates are provided with a protective film on both sides.
