I have an old metal box (6"x3"x1") w 12 compartments containing metal pieces from one half inch to about two inches, perforated for screws, and screws. They are stamped "Vitallium" On checking I find they were used in dental work and are made of 60% Cobalt, 20% Chromium, and 5% molybdenum. Have any of you worked this alloy before? I am still reading Hoak but these three metals have me stumped as to wether or not they are worthwhile.
