The demand for non-ferrous metal powders of higher quality, and produced with better control and lower costs, has lead to a demand for improved melt atomization techniques to be developed. The Russian company URALNETRAMM and the English company ATOMISIGN SYSTEMS Ltd have cooperated in the development of new methods to produce powders of Sn, Pb, Zn, Mg, Cu-Sn and other alloys with special properties, particularly narrow size range and fine particle size, while using very small amounts of atomizing medium and energy. The centrifugal-hydraulic atomization method(CHA) is a single-fluid atomization process using the e nerg of the fluid to atomize it in a swirljet (hollow cone) nozzle. This method allows the producton of powders from 100 mkm up to 1000 mkm with a standard deviation of the particle size distribution of 1.4-1.6 with outputs from 50 kg up to several tonnes per hour.
