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.
