Most stainless steels will not contaminate pickle, and most bronzes
shouldn’t either. There are some stainless steels in the low nickle
combinations that will contaminate and are also subject to light
rusting. I don’t know all about bronze alloys. The standard alloy
is copper and tin, but phosphorous, aluminum, and other metals are
often added to create bronze alloys for specific applications.
