Plewes, J.T. 9-4 AN ARTICLE OF MANUFACTURE COMPRISING A BODY OF CU-NI-SN ALLOYS CAPABLE OF BEING SHAPED BY MACHINING Abstract of the Disclosure This invention relates to an article of manufacture comprising a body of Cu-Ni-Sn alloys which are particularly suited for shaping by machining, such as drilling and lathing. In addition to Cu, Ni, and Sn, these alloys contain specified small amounts of Te, Se, Pb or MnS. When articles are formed by machining of alloys having such specified composition, clogging of the machining tool and overheating of workpiece and machining tool are effectively prevented. These alloys may also contain the usual impurities and/or other intentional additives in a total amount up to 10 percent of the alloy, and may be additionally treated to impart spinodal structure.
