Precious/Non-precious powders

Precious/Non-precious powders

SAFINA, a.s. offers the wide range of metal powders especially for different types of additive manufacturing based on the highly turbulent market. We use the whole spectrum of the manufacturing methods like a gas atomizing or hydrometallurgical processes.  We are focusing on customized production according to a manufacturing method and demands of customers. It is worth mentioning newly developed coated metallic powders (core-shell technology). The coated powders are made by hydrometallurgy, also we are working hard to develop powders coated by PVD (physical vapor deposition). Our competitive advantages are flexible production, which ensures short delivery time and the tailor made powders for customer samplings and trials.

Precious/Non-precious powders

Atomized Powders

  • Cu powders – atomized copper powder (purity 99,95 %) has high flowability, electrical conductivity, minimal amounts of satellites and very low oxygen content. Wide spectrum of copper alloys is possible to produce.
  • Ag powders – highly pure (4N) silver powder and its alloys with very good flowability and extremely low oxygen content are produced in SAFINA by our gas atomizer.
  • Au and PGM powders -  SAFINA is specialized for precious metal production, so we can offer special powders from Au, Pd and Pt for different fields of additive manufacturing. Of course, we are able to process wastes from your precious metal powder production.

Chemically precipitated powders

  • Silver powders – prepared by reduction from silver nitrate solution in a large range of particle sizes with dendritic shape. We are able to modify powder properties (e.g. particle size distribution, apparent density, tap density, flowability) to meeting particular customer requirements. The powders are commonly used in the fields of sintered contacts, carbon brushes, EMI/RFI shielding, and many others.
  • Gold, palladium, platinum powders – purity of these powders is 99.95 % or higher, powder parameters can be modified according to customer requests.

Coated powders

These powders are prepared by an electrodeless wet chemical coating process. Powders of different materials (e.g. Cu, Al, SiO2) and shapes (e.g. spherical, flakes, dendritic) coated by silver are commonly used to save costs and to keep their electrical and thermal conductivity at the level comparable with pure silver. We can offer for instance silver coated copper (Ag/Cu) and glass (Ag/SiO2), and we work hard further on development of other coated powders for our customers (e.g. Ag/Al).  

Please, do not hesitate and contact us, we are looking forward to developing new products for our customers. We are happy to send you a testing sample of our products.
