Description

This paper covers the description of defects in copper wire which result from the melting and casting operation, rolling and pickling operation and entire wiredrawing operation (rod breakdown, intermediate and fine wiredrawing operation). The paper also describes the morphology of surface and subsurface defects produced by rolled-in oxides, and possible implications due to rod grain size and impurities present in the copper. The effect of trapped impurities during the cathode electrolytic process will be discussed as well as surface defects produced in the wire.
