What is the hardness of 2024 alloy?

I agree with your assessment of 2024 hardcoat hardness. We know from our experience that it is significantly softer than 6061 but we do not have any test numbers. The general principle is that the higher purity alloys will always yield a denser and harder hardcoat...

Can you hide machine marks or scratches in anodizing?

A principle to keep in mind is that whatever you have on the machined finish will remain after anodizing or chromate conversion. Think of the anodizing process as similar to film development. Whatever is in the substrate of the aluminum will be more visible after the...

Can hardcoat anodizing be reprocessed?

Question: “Can hardcoat anodizing be reprocessed?” Answer: The short answer is yes, however Type III anodizing can present a number of potential issues to consider before reprocessing parts that have been hardcoated: Dimensional Change: Reprocessing...

Anodizing – What is it?

Anodizing Process Overview Anodizing is an electrolytic process for producing controlled aluminum oxide films on aluminum. Oxide forms naturally on untreated aluminum, but the anodizing process produces a coating which is uniform, much harder, and more dense than...

Dimensional Growth During Anodizing

How much dimensional growth from anodizing should be expected? Anodizing is the process of electrochemically converting the surface of an aluminum part to aluminum oxide. Aluminum oxide occupies about two times the volume as that of raw aluminum. Therefore, anodizing...
