On the Platinum writing instruments, the basic material consists, depending on the component, of different materials: the tip is copper-plated brass with platinum plating, the rings are made of rolled gold (thick gold layer on brass) and additionally platinum-plated, the clip is made of nickel silver (Alpacca, copper-nickel-zinc alloy). With extremely heavy use and frequent polishing, the coating can wear off; with normal use, however, no problems are to be expected even after years. Anyone wishing for a continuously metallic construction can reach for the stainless steel variant.
