Consistent Specs, Reliable Lead Times — Controlled Electrodeposition for On‑Spec Lots (Powder, Flakes, Mesh Ranges)
Summary
We offer electrolytic copper powder and flakes manufactured via electrochemical deposition (electrodeposition). The product features a dendritic morphology, associated with low apparent density and high specific surface area, making it suitable for conductive and powder-metallurgy applications.
High‑Purity
Electrolytic Copper Powder (≥99.90% Purity) for demanding industrial applications.
Dendritic Morphology
Branched, tree-like particle structure for conductive & powder‑metallurgy applications.
Repeatable Performance
Controlled electrodeposition for on‑spec lots across powder, flakes, and mesh ranges.
Technical Capabilities
1) Purity and Composition
Purity commitment: ≥ 99.90%.
Typical reported composition (example): Cu 99.989%.
Typical reported trace elements (example): Sn 0.001%, Pb <0.001%, Zn 0.002%, Fe 0.003%, Ni <0.001%, Al <0.001%, Ag <0.001%.
Note: Chemical composition may vary and other elements may be available.
2) Morphology
Shape: Dendritic. This means particles have a branched, tree-like structure with many "arms," which increases surface area and can influence compaction behavior, conductivity, and performance in powder metallurgy and friction materials.
3) Typical Particle Size Distribution
A typical distribution is reported by size ranges (µm) with mass percentages.
Note: Particle sizes are approximate and distribution can be adjusted based on the target application.
