Electrolytic copper powder

Copper Electrolitic (Reduced)

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

Product families

Copper Cu SA-SB-SE-SF
High purity copper powder with high specific surface
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.
