Process: electrolysis of raw copper, annealing (oxide reduction), sieving
Composition: copper content of 99.5 / 99.8%
Apparent densities: 2.00 g / cm3 up to 3.20 g / cm3
Particle shape: dendritic (high specific surface)
Particle size distribution: 630 to 32 microns
| Description of the material and main chemical components | High purity copper powder with high specific surface |
|---|---|
| Description of the manufacturing process | Powder from electrolytic processing starting from qualified raw material, annealing, sieving, (possible) mechanical treatment |
| Typical applications | Metallurgical corrections, diamond tools, friction, chemical, welding, ferrous and non ferrous sintering, jewellery, carbon brushes |
| Particle shape | Dendritic |
| Main characteristic | Characterised by high purity of content, and high specific surface of powder with good reactivity to most uses. When mixed in sintering blends it brings compressibility, green resistance and help controlling dimensional changes |
| Particle upper cut size (full range) | 63 to 180 |
| Particle upper cut size (typical) | 63 to 180 |
| Apparent density (typical) | 2,00 to 2,40 |
| Application notes | Used wherever highest % of Cu is necessary. Compared to non reduced Cu electrolityc have better Flowability. Powder tends to get oxidised if stored for long. |
