Zirconium Oxide (Zirconia) is the toughest ceramic commercially available. We actually have a hammer made out of this ceramic. This high-strength material exhibits excellent wear and corrosion properties. The material can also be HIP'd for added strength and edge retention. Zirconia exhibits a very low coefficient of friction and is available in MgO or Yttria stabilized grades. 

Common applications include:
      - Ceramic razor blades
      - Catalyst Extrusion Dies
      - Sucker Rod Balls and Seats
      - Wear Bushings
      - Valve Trim
      - Orifice plates
      - Guide Rollers and sleeves in metal
      - Computer drive components
