Ultra High Pressure Swirl Water Atomized Super Fine Powder [HWQ]

In order to manufacture the powder particles with a fine spherical shape, technology was developed that uses a high-pressure rotating jet of water for atomization. This enables mass production of powder with a small mean particle size and minimal aggregation.

Main ingredients Cu (copper) Ag (silver) Sn (tin) Fe-based (iron-based)
Manufacturing method Ultra high pressure swirl water atomization
Shape Spherical

Due to the fine size and spherical shape of particles, this powder offers low aggregation. Therefore, it is suitable, for example, for use in MIM and other powder metallurgy applications, for use as a conductive paste for electronic circuitry or capacitors in electronic fields, or as a bonding material for diamond tooling applications.
