DEFINITION

Classification: 75/247

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

(under subclass 246) Composition in which half or more of the composition, by weight, comprises one or more, exclusively, of Copper (Cu) or Noble metal (i.e., Silver (Ag), Gold (Au), Osmium (Os), Iridium (Ir), Platinum (Pt), Ruthenium (Ru), Rhodium (Rh), and Palladium (Pd)).
