title: Physical properties of a repeatedly used nonprecious metal alloy.
abstract: Some physical properties of nonprecious alloys were compared after repeated casting without the addition of any new alloy. The tensile strength, percentage of elongation, and hardness properties were determined and compared. There were no significant differences observed in the physical properties tested among any of the four generations of casting. This finding indicates that the metal can be reused for at least four generations.
