Nozzles for Gas Automized Powders Making

Performance

  1. Excellent corrosion resistance and wear resistance, resistant to corrosion of stainless steel, copper, aluminum, iron silicon aluminum, iron silicon nickel, iron nickel and other alloys.
  2. The highest using temperature is 1750℃, and the using life is long.
  3. Strong thermal shock resistance, high temperature alloy solution instant repeated scouring without cracking and deformation.
  4. The formula can be independently designed according to customer requirements.
