Atomising Nozzles

Capital produces a wide range of atomising nozzles in a range of zirconia and zircon materials. These are suitable for use with a wide range of alloys including aluminium, lead, iron, steels and superalloys. Our nozzles comprise high dimensional accuracy, erosion resistance and controlled porosity. Additions of calcium, magnesium and rare earth oxides are used in zirconia compositions as stabilising agents to enhance thermal shock resistance and corrosion/ erosion resistance. Composite nozzles are also available which combine an erosion-resistant insert (high fired ceramic bonded), with a chemically bonded high alumina or zircon outer. 

Advantages of the AtomiZIR Nozzle

  • Stable flow characteristics achieved through close dimensional control and erosion resistance
  • Suitable for both water and gas atomisation of ferrous and non-ferrous metals
  • Excellent erosion resistance combined with the reduction of cracking from thermal shock
  • Can be used in a variety of casting environments
