In the anodizing industry, some people are using titanium racks and
some are using aluminum racks. Why? What is the main difference? On
the surface, Ti racks cost more, (5-9x) but last a lot longer.

Actually,titanium works better in the alkaline solution,while in the acid the aluminum should be fine.
