Air atomised spherical copper powders produced with careful control of chemical composition and good batch to batch reproducibility.
Available in a range of particle sizes with excellent size distribution control, good sphericity, low oxygen content and low lead (Pb) content.
Spherical copper powders are used in many applications including diamond tooling, anti-fouling paints, friction components, metallurgical alloying, welding and brazing, and decorative applications such as cold casting and cold metal spraying.
The table below represents specifications for some typical copper grades, other sizes are available.
| Description | Composition (%) | App Density (g/cc) | Size (μm) |
|---|---|---|---|
| Spherical Copper -100# | Cu>99.3 | 5.0 ± 0.5 | <150 |
| Spherical Copper -200# | Cu>99.3 | 5.0 ± 0.5 | <75 |
| Spherical Copper -300# | Cu>99.3 | 5.0 ± 0.5 | <53 |
