Purity : the purity of copper nuggets is > 99.99%
Dimensions : diameters : 5, 8, 10, 12, 16, 20mm – length : from 5 to 40mm
Product description : to respond to your needs, we offer several diameters for copper mini-cylinders: 5, 8, 10, 12, 16 and 20mm. We also adapt the length: from 5 to 40mm. Other dimensions are also possible, do not hesitate to ask us.
We offer different copper grades :
- Electrolytic copper nuggets – ETP copper : made from copper that is more than 99.99% pure, they are used for copper sulphate baths and copper pyrophosphate baths. They are still used for baths containing sodium or potassium cyanide with copper cyanide.
- Oxygen Free copper nuggets – 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 nuggets – 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.
