Stripping Tin from Copper
Q. I recently received some old tin-plated copper to be replated. What methods can remove the old tin layer without harming the copper? S.Y.
A. The usual method for stripping tin from copper is to use a sodium hydroxide solution with a concentration of approximately 100 g/L at 75–150°F. The part to be stripped is made anodic and a steel anode is used. Voltage should be approximately 6v. If the temperature of the solution is too high, the copper base will be
Our expert, Art Kushner, says yes, you can color stainless steel, but it is not a process that is typically performed in a plating shop. Read more about his answer.
