Aluminum corrosion while touching stainless steel 304

I have aluminum touching stainless steel 304.Should I anodize the aluminum or to do other process in order to prevent corrosion.

Hi, Danny. Bare aluminum usually has no corrosion resistance, so you must do something; and anodizing is a good corrosion resistant finish, and sufficiently dielectric to help somewhat in the galvaniz corrosion issue.
