Cast high chromium

Superior grinding performance

Magotteaux mining grinding media cast high chromium combining a martensitic structure with hard chrome carbides provides the optimum wear resistance against abrasion and corrosion. Our strong expertise is enabling us to select the right alloy to fit your application and minimize the costs.

  • Steady milling conditions due to low wear rate
  • Constant hardness of all grinding media for each alloy
  • Positive influence of down-stream process
