In the anodizing industry, some people are using titanium racks and

the surface, Ti racks cost more, (5-9x) but last a lot longer.

Titanium is inert in the process. Aluminum racks undergo anodizing
themselves.

Further: when aluminum racks become anodized, they are no longer
conductive on their surfaces so work hung on them is not connected to
the power supply and doesn't get anodized.

Thank you for your responses. Aluminum racks cost more in long term.
During the anodizing process, aluminum racks have to be stripped each
time after use. Why would every anodizers use titanium racks?
