Copper & Cu Alloy Spherical Powder

New product

Spherical copper and alloy powder is an ultrafine metal powder with high dispersibility, high filling property and uniform particle size. Due to its excellent dispersibility and good adhesion with resins and solvents, this product can shorten the necessary mixing time and achieve a high degree of product uniformity.

COPPER ALLOY and Cu Spherical Powder

Alternative designation: C10200 or CW008A

Description and material properties:

OF-Cu is an extremely pure, oxygen-free Copper with a minimum of 99.95% Cu. It combines the advantages of Cu-ETP and the phosphor deoxidized Copper materials. The high pureness of the material combined with missing oxygen inclusions allows a 100% IACS electrical conductivity and is not affected form hydrogen embrittlement. OF-Cu has good deformability, solder- and weldability, better than Cu-ETP. Typical applications are electrical and electronic components and the communication industry.

Powder production:

We developed a unique powder production process to provide perfect spherical powders (patent pending). Any metal or alloy can be atomized according to your needs. Our processes are run with Argon as atomization gas in a dust-free production environment to guarantee maximum product quality. Any process (production, classifying, screening, packaging) can be done under Argon 5.0, so oxygen-free production can be guaranteed. 

Powder screening:

With various screening technologies (Cucciolini, Russel-Finex, Kellner) we can screen your powder at grain sizes from 10 to 1000 microns. 

Powder classifying:

With our state-of-the-art classifiers (Noll) we can provide narrow particle size distributions, produce ultrafine powders (d99<5 microns) or remove dust from your powders. 


We pack the powders according to your needs and manage transport organization.
