5083 Precision Ground Aluminum Plate

Chalco’s 5083 precision ground aluminum plate has fairly balanced and superior processing characteristics. Its particle structure is precise and the porosity is extremely low. By adding heat treatment, the internal stress of the material is eliminated and becomes more uniform. At the same time, its dimensional stability is perfect.
