For numerous applications and a wide spectrum of alloys
The AUG machines are designed for numerous applications in the most diversity thanks to their narrow particle size distribution and high yield and the possibility of flexible usage provided by different nozzle systems. They are generally suitable for gas atomization of a wide spectrum of alloys; such as those based on Cu, Au, Ag, Sn, or Zn (standard versions) as well as Fe, Co, Ni, Pd, or Pt (high-temperature versions HT, HTC, and HTC+). The inductive heating takes place in graphite crucibles (up to 1600° C) or in ceramic crucibles: HT up to 1750º C, HTC up to 1850º C, HTC+ up to 2000º C. The crucible volumes reach from ~1.5 l to ~25 l. For the production of reactive materials like Al or Mg, please ask us for our solutions.
Powder characteristics and particle sizes for every request
To obtain specific metal powder characteristics and particle sizes, the AUG machines work with different easy-to-change nozzle systems: free-fall and close-coupled atomization nozzles. Optionally, an anti-satellite system for highest sphericity is available.
The AU machines offer the possibility of oxidation-free processing in the closed-chamber machine by means of de-gassing, vacuum and protective gas features.
Gas flow optimisation
Increase of powder quality by gas flow optimisation in the spray chamber (avoidance of satellites)
Specific powder characteristics
by use of different atomisation nozzles and optional use of hot spray gas
Modular availability of free fall as well as close coupled atomisation nozzles to obtain specific metal powder characteristics. Fast and easy nozzle change.
Polished stainless steel surfaces prevent powder adhesions in spray chamber, cyclone and collector – all parts are easy to clean without any residues.
Dynamic Differential Pressure system for constant metal mass flow
The DDP system is ensuring a constant and controllable metal mass flow, and therewith gas-to-metal ratio, independent from the melt level in the crucible.
