ACP 5080P
Industry leading flatness and tolerances combined with excellent dimensional stability.
High precision low stress aluminium cast plate, ACP 5080P, is precision surface machined on both sides to industry leading precise tolerance standards. Fine grain structure, low porosity and excellent machining characteristics all define the cost saving and value-added attributes of ACP 5080P. Superb industry leading material dimensional stability is inherent in every plate of ACP 5080P; thanks to proprietary processes and manufacturing control, our flatness and tolerances are industry leading, predicable, and precise. Each plate is inspected and protected on both sides finally.
