Product description : to respond to your needs, we offer several diameters for copper balls ranging from 15 to 60 mm.
Made from the purest copper cathodes, the balls are placed in rectangular or cylindrical titanium baskets, depending on their size.
Due to their spherical shape, the circulation of copper solution is homogeneous and thus prevents the formation of bridges in the baskets. The anodic surface also remains constant thanks to very easy maintenance. As always, in order to retain residues, an anode bag will be placed around the basket.
Finally, 100% of the copper is consumed and there is no scrap to manage.
We offer different grades for copper balls :
- Oxygen Free copper balls – OF copper : their particularly low oxygen content, always less than 5 ppm, corresponds to special applications. Their advantage is the very low formation of electrolytic sludge compared to electrolytic copper. OF copper is dissolved in copper sulphate acid baths and also formulations with potassium pyrophosphate and copper pyrophosphate. It is also used in baths based on potassium cyanide or sodium cyanide also containing copper cyanide.
- Phosphorous copper balls – DXP copper : this slightly alloyed copper quality is used for glossy copper coatings or as a sub-layer before a nickel layer. Also known as DHP Copper or DXP copper, it contains between 400 and 600 ppm of Phosphor. Anodes are placed in copper sulphate baths.
Uses : copper balls are used for electrolytic copper plating. Depending on the type of copper deposit you want (mat, gloss, ductile, etc.), different copper qualities will be used: Oxygen free or phosphorous.
When used, the copper balls are put into titanium baskets with an anode bag around them.
