Abstract
Cu-Ni-Sn alloys are disclosed which are particularly suited to undergo 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.
