This is for a home project that relates to what I've been studying in school. It involves a metal strainer, I'm trying to figure out if it is stainless steel since if it is any other metal, it may pose some serious problems for straining kefir or other things. This strainer is all mesh, and the only solid parts are made of plastic unfortunately, so that has complicated a few ways of testing it to see if it is stainless steel or aluminum(like trying to scratch or dent it with a brass key). It's not magnetic, and many if not most forms of stainless steel are non-magnetic, while virtually all aluminum is non-magnetic. It doesn't become duller after washing thoroughly, as would many forms of aluminum. I would appreciate as many ways of testing the metal as possible, and I would love to understand the science behind it to help me in my schooling and teaching others.
