The ultrafine copper powder UF5 NMD Metalpowders is a high-quality metal powder for industrial manufacturing processes that require a defined particle size and reliable material quality. With a D50 particle size of 3.0–5.0 µm and spherical particles, it serves as a raw material for electronic applications, functional coatings and selected powder-based manufacturing processes.
Copper’s high electrical and thermal conductivity makes UF₅ an attractive material for the development of conductive material systems. The properties achieved by the finished components depend not only on the quality of the powder but also on the composition and processing.
Technical properties
- Particle size (D50): 3.0–5.0 µm
- Particle size (D90): ≤ 10 µm
- Particle size (D100): ≤ 15 µm
- Grain shape: Spherical
- Purity: High purity; detailed chemical specification available on request
The D50 value describes the median of the particle size distribution. Together with D90 and D100, it enables the particle size to be matched to your processing specifications. Other selection criteria include flow behaviour, dispersibility and the surface condition of the particles.
