It doesn't always have to be silver ...

---

 

DODUCO also offers silver-plating of various copper powders. This surface treatment permits elementary improvement of the properties of the basic material of copper, in particular corrosion resilience, electrical conductivity and soldering capacity of the material.

 

The possible uses of the powder are determined by factors such as grain size, grain shape, bulk density and silver content. Of course, the powders named below are only examples. Specific powders can be implemented according to the customer's requirements.

 

 

Coarse powders have diverse uses in the production of carbon brushes.

 

               

 

Finer, electrolytic powders, in contrast, are found rather in electrically conductive silicones, plastics, varnishes, paints and pastes that can be used, among others, for electromagnetic shielding.

 

                 

 

Thus, refined copper powders not only offer the option of substituting pure copper to improve the product properties, but may also permit an additional more cost-efficient alternative for pure silver powder, depending on application.
