Balls


Final Advanced Materials provides a range of ceramic balls with corrosion and abrasion resistance at high temperature in alumina Al2O3 and zirconia ZrO2.



Zirconia ZrO2 Ceramic balls presentation


Our zirconia ZrO2 (3% MgO stabilized) ceramic balls guarantees excellent mechanical properties, very good wear and corrosion resistance. Zirconia balls can be used up to three time longer than the equivalent in carbide or metal in application with high corrosion and wear.
