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.
Our gas atomizers produce spherical, flowable metal powders with mean particle sizes between ~1 and 200 µm for e.g. additive manufacturing, soldering or foam sintering processes, as well as MIM and other powder metallurgy procedures.
Oxidation-free processing for maximum cleanliness
The AUG and as well the AUW machines offer the possibility of oxidation-free processing in the closed-chamber machine by means of de-gassing, vacuum and protective gas features to realize highest cleanliness. Oxygen sensor values below 0.5 ppm can be achieved reproducibly.
The Gas Atomizer – at a glance:
- Very simple handling via LCD-Display and neatly arranged control panel
- Flexible and economic production of small to medium metal powder batches
- Easy-to-clean concept: minimum metal loss and cross-contamination
- High powder yield over a particularly wide particle size range
- Particularly high process stability due to optimized nozzle systems
- Anti-oxidation features

Gas separation by treatment in cyclones, minimum risk of powder agglomeration
Water-cooled parts like spray tower and cyclone for fast cooling of the atomized material, optionally in combination with a passivation feature to avoid agglomerations especially of soft and high purity materials like Cu, Ag, Au, and/or in case of very fine powders (diam. ~< 20 µm).
