5083 Precision Ground Aluminum Blanks

Chalco 5083 precision ground aluminum blank, its flatness is very good, it reduces the thickness of the plant and the residual stress, can reduce the cutting workload, and reduces the stress-relieving annealing process, which greatly improves the processing yield and contributes to cost savings for customers.
