Zirconium Oxide - AmZirOx 86 Zirconia Ceramic
AmZirOx 86 zirconia (Astro Met Zirconium Oxide) is a yttria stabilized zirconia ceramic material which features high strength and toughness making it a candidate material for use in severe structural applications which exhibit wear, corrosion, abrasion and impact. This material is also commonly referred to as Y-TZP or Yttria Tetragonal Zirconia Polycrystal. AmZirOx 86 zirconia has been developed with a unique micro structure utilizing transformation toughening which allows AmZirOx 86 zirconia to absorb the energy of impacts that would cause most ceramics to fail. AmZirOx 86 zirconia components can be fabricated into a wide range of precision shapes and sizes utilizing conventional ceramic processing technology and finishing techniques.
