DEFINITION

Classification: 75/246

Base metal one or more of Iron group, Copper (Cu), or Noble metal:

(under subclass 245) Composition in which half or more of the composition, by weight, comprises one or more metals selected exclusively from the Iron Group (i.e., Iron (Fe), Cobalt (Co), Nickel (Ni)), Copper (Cu), or Noble metal (i.e., Silver (Ag), Gold (Au), Osmium (Os), Iridium (Ir), Platinum (Pt), Ruthenium (Ru), Rhodium (Rh), and Palladium (Pd)).

(1) Note. Compositions containing steel, cast iron, etc.,

are considered to be nonmetal containing, and are classified in subclasses 230+. See the definition of subclass 230.
