Powder Atomizer

AMAZEMET rePOWDER

rePowder is a commercially available Ultrasonic powder atomizer machine for metals and alloys.

rePowder, unlike gas atomization systems, uses ultrasonic vibration for metal atomization. Metal is poured or melted directly on the vibrating part resulting with tiny droplets being ejected from the surface. Droplets solidify in surrounding inert gas atmosphere forming powder particles. The result are highly spherical metal powders with narrow particle size distribution – up to 80% is good to use in desired processes.

  • Induction melting is used to process alloys with melting points up to 1300 °C, for example:
  • relatively low melting point and volatile materials that tend to evaporate in the plasma, such as Sn, Zn, Mg, Pb, and Al alloys,
  • materials with high thermal capacities and conductivities, including precious metals like Cu, Ag, and Au alloys.
  • Arc / plasma melting is suitable for working with all medium and high-melting materials including:
  • ferrous alloys,
  • Ti, Ni, Pt, Ir based alloys,
  • refractory metals such as W, Ta, V, Mo, Nb, Re, etc. including High Entropy Alloys,
  • metal matrix composite powders and amorphous metals.
