<p>Articles of copper or copper alloy are anodically deburred in an acid solution (pH not above 6.5) containing: water 100 to 300 g/l; alkali sulphamate 50 to 150 g/l; polyhydric alcohol 400 to 800; alkali nitrate 50 to 150 g/l. The bath voltage is to be within the range of 5 to 30 volts, and the current density (at the anode) is to be within the range of 2 to 50 amperes per square decimeter.</p> |
