ACP 5080
Industry leading flatness and tolerances combined with excellent dimensional stability.
High precision low stress aluminum cast plate, ACP 5080, 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 5080. Superb industry leading material dimensional stability is inherent in every plate of ACP 5080; 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.
