Copper Anodes

Tamra manufactures high purity copper anodes in different shapes and sizes for electrolytic copper plating. Nuggets and bar anodes are produced by a continuous casting process, while balls are produced by forging. After fabrication and sizing, the anodes are cleaned and washed so they are ready to use when they arrive.

Tamra provides two grades of copper to meet the needs of most plating. The oxygen content of oxygen free anodes is controlled to less than 10ppm to provide uniform dissolution in cyanide, pyrophosphate and fluoborate baths. Phosphorised copper anodes containing 0.04-0.06 percent phosphorus are required for acid copper solutions.

Nuggets are the most common form of copper anode. They are typically 1” in diameter by one-inch-long, but other sizes are available. Both OF and Phosphorus copper nuggets are available.
