Anodes
Excellent solutions for plating industry
Electroplating is widely used in various industries for coating metal objects with a thin layer of a different metal. Electroplating can change the chemical, physical, and mechanical properties of an item.
Luvata is a leading supplier of copper anodes for electroplating. Our copper anodes are manufactured from the purest electrolytically refined copper cathodes, which are melted under strictly controlled conditions to guarantee even alloying.
Each casting of both oxygen-free copper anodes and phosphorous copper anodes is made under highly controlled and optimum conditions. This leads to the lowest variation in structural and chemical properties and therefore predictable electrical conductivity, plating and ductility performance.
Our anodes have been designed to ensure low sludge development, stable copper content in plating, a rapid build-up of the adherent anode film to allow problem-free start-up of a new bath and a low build-up of impurities in the bath.
The benefits of Luvata anodes include:
- Ultimate high purity level
- Good dissolubility
- Even quality
- Full traceability
- Low tendency to passivation
- Low sludge development
- Low consumption of additives
Round and smooth ball anodes are very easy to handle as they are free flowing.
Our manufacturing process guarantees anodes behave exactly the same way - from plating bath to bath.
Common applications include
- Coin blanks
- Rotogravure printing cylinders
- Printed circuit boards
- Decorative plating
- Radiators
- Automotive parts
Oxygen-free copper
Oxygen-free copper anodes are manufactured from extremely pure copper (99.95%). These anodes are used for the alkaline plating processes in cyanide and pyrophosphate baths.
Oxygen-free copper has no pores in the cast state and no copper oxide inclusions.
We have considerable expertise in electrochemical processes and works closely with both the chemical industry and plating line producers to continually improve products and production methods.
Phosphorous copper
The phosphorous content of these anodes is P 0.04 - 0.06%. In our casting process, phosphorus is added to the master alloy which melts very fast. Due to diffusion and continuous movement of the copper melt, the phosphorous is instantly evenly distributed in the melt. This leads to even phosphorus content in each anode.
Our phosphorous copper anodes are widely used in the plating of printed circuit boards (PCBs) and in acid copper plating baths.
