ACP 5052

Alimex Cast Plate 5052 is a tight tolerance surface machined plate with exceptional strong visual and aesthetic qualities after surface treatments are applied.

The ultra fine homogeneous grain structure ensure that a very consistent appearance is achieved after anodizing. Alimex Cast Plate 5052 offers excellent material stability for even the most aggressive CNC milling operations. Alimex Cast Plate 5052R is the saw cut version of the alloy which is recommended for applications in larger plate dimensions or where surface machined top/bottom surfaces are not necessary.

Ultra-high-precision flat-sided aluminum plate ACP 5052 after finishing milling, its precise flatness tolerance standard is an industry leader. Its grain structure of precision, low porosity, and has balanced superior processing characteristics. Anodic oxidation in terms of performance even more than the ACP 5080. This product is particularly suitable for both materials need balanced structure and excellent machining performance, with special emphasis on the aesthetics of the surface application material after the subsequent processing.
