Project Description

Sample Products

  • Ceramic Insulators

Ceramic Insulators

  • our ceramic plungers are fabricated from Alumina Oxide, Zirconia Oxide, Silicon Nitride and Silicon

Ceramic Plungers

Zirconia oxide

Zirconia oxide 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 Zirconia oxide maintains efficient manufacturing facilities that support quick-turn prototype development and high volume production.
