Copper processing

 · Typical samples of electrolytic copper contain from 99.92 to 99.96 percent copper. About 0.03 percent oxygen is purposely left in the copper, since this amount slightly improves the density and conductivity of the metal. Copper in this condition has a conductivity of 100 to 102 percent of the International Annealed Copper Standard.
