If we must use copper alloy scraps to make copper alloy castings, the author will advocate the Limebabbling process which means use of calcium carbonate chips at the bottom of the molten bath. This process improves the mechanical properties of copper alloy which is made with scraps, that is, the tensile strength 19%, and the elongation 72%. And the content of hydrogen decreases 25%.
