Abstract
A method for adding reactive elements to molten copper or copper base alloys is disclosed. This method prevents unwanted reactions and oxidation by adding the reactive elements to the molten metal in the form of a powder mixture placed within tubing which is compatible with said molten metal. This filled tubing is sealed and drawn down, if desired, to an appropriate size for rapid melting within said molten metal and consequent rapid dissolution of the reactive elements throughout the molten metal.
