Zirconia (ZrO2) – Custom Machined Parts
Zirconium Dioxide, commonly known as Zirconia, is a high-performance ceramic material which exhibits excellent mechanical properties such as high hardness and fracture toughness. This makes zirconia ideal for a variety of wear resistance applications.
It is difficult to manufacture zirconia in large sizes compared to other oxide materials like alumina. In addition, zirconia is a relatively expensive material, and its use is usually limited to small parts / components which require high bending strength and resistance to fracture, chipping and cracking.
