Indutherm, based in in Walzbachtal, Germany, has developed a new metal powder atomiser suitable for small batch gas atomisation of alloys based on Cu, Sn, Au or Ag. The AU 1000 is a closed unit that offers the possibility of oxidation-free processing by means of a protective gas supply, with planned options for crucible volumes between 0.3 to 12 l.

Inductive heating takes place in graphite crucibles up to a maximum temperature of around 1500°C – 1600°C. The aim of the modular system, with various easily exchangeable atomisation components and optimum use of hot atomisation gas, is to cover a very wide range of powder sizes with this facility. Development has already started on the design of an atomiser for higher temperatures and alloys based on Fe, Co, Ni and Pd.

In 2012 Indutherm began development of a powder atomisation facility in collaboration with the University of Bremen, Germany, sponsored by the Federal Ministry for Economics and Technology. In 2013, the prototype was built at the University of Bremen and testing began.

The Indutherm Atomiser System was presented at the Hagen Symposium 2013 and the SDMA 2013 in Bremen. Since the beginning of 2014 the company has developed a near production model at its facility in Walzbachtal. The company states that models from the AU series (Atomising Unit) will shortly be available for sale.
