Aluminum 5083 Anodization
Aluminum 5083 Anodization
(OP)
Hi,
As far as I know, hard anodizing cannot be perceived as coating. Taking this statement into consideration. I would like to know, from your experiences etc., whether it is expected that the dimensions of an aluminum part change after the anodizing or not.
Although we put the drawing note stating the dimensions apply after treatment. I still want to know if the dimensions and tolerances of the part change after anodizing.
The material is Aluminum 5083 and anodizing is per MIL-A-8625 Type III, Class 1. 0.0015-0.0025 inches thickness.
Best regards

What is the pre-anodizing dimension tolerance?
RE: Aluminum 5083 Anodization
Dimensions definitely change. In addition to the thickness of the anodic coating, the parts usually are etched. An anodize process can result in a net removable of material.
If your fabricator organizes anodizing, you need to specify tolerances after anodizing. Otherwise, you cannot inspect the parts. Your fabricator can talk with the anodizer about their process.
