ure copper has a number of useful properties: ductility, high electrical conductivity (next after silver), corrosion resistance in fresh and sea water as well as in certain chemical environments. Low yield stress and high cost of pure copper restrict the use of the metal as a structural material. About 50% of copper produced is used in electrical and radio engineering. Copper alloys are widely used as structural metals. Among these metals are brass, bronze, cupronickel and others. They possess good antifriction, technological and mechanical properties and are resistant to corrosion.
Performance of copper electrolyte-plasma treatment and polishing:
Recommended processing time for copper polishing — 180 sec.
Grinding and deburring speed — 20 sec.
Average time to reduce the roughness value by 1 class — 75 sec.
The number of polishing cycles before changing the electrolyte — 60.
