Round copper alloy

The normal End-Ring used for the high speed motor such as Traction Motor is easily deformed by both centrifugal force and high température during welding End-Ring and Rotor Bar together. To prevent this, we’ve developed spécial End-Rings with high tensile strength by advanced heat treatment and rolling technology. • Production Process Billet -► Cutting ■ Pre-heating ■ Hot torging ■ Solution heat treatment ■ Pre-scalping ■ Cold forging(small size) or Cold rollingtbig size : to have uniform structure and physical properties in the whole cross section) ■ Aging ■ Pre-Scalping ■» Extemal & Internai finishing by Endmill ■ Fine tinishing
