Zirconia Oxide Ceramic Manufacturing

 
Zirconia has the highest strength and toughness at room temperature of all the advanced ceramic materials. The fine grain size allows for extremely smooth surfaces and sharp edges.

Applications include scissors, knifes, slitters, pump shafts, metal-forming tools, fixtures, tweezers, wire drawing rings, bearing sleeves and valves

Ortech provides state-of-the-art materials manufactured by the most cost-effective processes. Ortech maintains efficient manufacturing facilities that support quick-turn prototype development and high volume production.
