AUS 500, the new Atomizer solution – from alloy creation to powder within 1 hour

The Ultrasonic Atomizer Unit enables almost anybody to produce small batches of high-quality, spherical powder for the same target application as gas atomized powder at an affordable price and without having a complex infrastructure.

The AUS 500 is available in different batch sizes from 0.25-0.7l. The melting and alloying of the material in the crucible takes place with an indirect induction system (e.g. graphite crucible) or a direct induction system for high temperatures (ceramic crucible).

The AUS 500 is compact and only needs a few squaremeters floor space.

Other Advantages of AUS-Serie

Footprint of just a few square meters including infrastructure

without any satellites for the highest powder fluidity and bulk density. Could be basically used as well for non-metallic materials (certain fluidity required).

due to precise control of the melting temperature via a crucible based induction heating system, while evaporation of alloy ingredients like Zn, Cr etc. is a common issue during plasma-assisted atomization.

No need for complex and expensive wire production as feedstock material for atomizing, which is time-consuming and requires additional infrastructure like continuous casting machines, a drawing bench etc.

for evaporated alloy ingredients otherwise caused by plasma melting

In development: e.g. larger version offering a crucible volume of 1.5 l

Yield for example for Bronze d50= 40-60 µm. Bronze throughput up to several kg/h.Very small batch sizes down to ~100 g technically and financially viable.

Alloying with a good stirring/mixing effect due to strong medium- frequency induction generator with simultaneous high heating efficiency. Melting under vacuum or inert gas atmosphere and atomizing under inert gas atmosphere.
