Zinc-coated wire OS-Z wire * This zinc-coated wire consists of brass wire electroplated with high purity zinc. The high plating accuracy realizes faster machining speed and also provides a better surface finish on the work piece. * The high purity zinc layer formed on the surface of the brass by means of our unique electroplating technology realizes higher machining speed. * By uniformly coating the surface of the wire with zinc, which has good discharge characteristics,it is possible to create a finer discharge compared to when using general brass wire. In the finishing process, improved surface roughness and a better machined profile are obtained,resulting in high cost performance. * Almost no copper adheres to the work piece. * The zinc coating method is a method of coating by electroplating. It is not a method in which is wire is dipped in molten zinc. * A high purity uniform zinc layer can be obtained. * The discharge is stable and free of irregularities. * Impurities are kept to the minimum, thus preventing deterioration of performance.
