Copper Flakes
Copper (Cu) · Copper Powder Flakes · Metallic Copper Flakes · Copper Granules
Copper flakes are thin, irregular metallic particles produced through atomization, milling, machining, or recycling processes. Their high conductivity and large surface area make them valuable in electrical, chemical, and industrial applications. Depending on particle geometry, copper flakes can exhibit unique flow characteristics compared to spherical metal powders. The material is dense, prone to segregation, and capable of generating metallic dust during handling. KWS designs enclosed conveying systems that provide consistent flow, minimize product degradation, and prevent contamination of high-value copper materials.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Metallic Flakes, Chips, Granules, Powder Blends |
| Bulk Density | 80-180 lb/ft³ (depends on flake geometry and compaction) |
| Flow Behavior | Moderately free-flowing; irregular particle shape can cause interlocking and bridging |
| Abrasiveness | Moderate Metallic particles may contribute to equipment wear |
| Corrosiveness | Low Copper is corrosion resistant but may oxidize when exposed to moisture and air |
| Dust Potential | Moderate to High Fine metallic particles require containment and housekeeping |
Handling Challenges
- Bridging and inconsistent flow due to irregular flake geometry
- Segregation during conveying and storage
- Dust generation from fine metallic particles
- Product contamination concerns in specialty and high-purity applications
- Material oxidation from prolonged exposure to moisture and air
