Ceramic Materials



Ceramic Materials Examples

C-Mac International LLC manufacturers tight tolerance ceramic parts for engineered applications where advanced technical ceramics are required; materials ranging from steatite to 99.%5 alumina.

Refer to our complete list of ceramic materials and or specific page details for advanced technical ceramics such as Zirconia (MgO stabilized and Yttria stabilized) or Alumina (90%, 96% and 99.5% pure) and custom ceramic application requirements.

Alumina – Aluminum Oxide

Alumina is a very hard, dense material of exceptional strength. Alumina exhibits resistance to both high temperature and corrosion. Electrical properties of alumina include high volume resistivity as well as low loss characteristics at high frequencies. We produce many grades of Alumina products by injection molding, dry pressing and extrusion processes.

Steatite – Crystalline Magnesium Silicate

Steatite ceramics exhibit excellent electrical properties. By manufacturing different grades of Steatite, we can meet a variety of electrical and mechanical requirements. For general applications, specify L-3. For applications where low electrical loss is critical, specify L-5. The capability to manufacture a wide range of extruded sizes accommodating both resistor and igniter manufacturers. Superior manufacturing capabilities allow us to produce complex products to accommodate the heater and appliance industry.

Zirconia – Zirconium Oxide

Zirconia is a very hard and durable material, with low thermal conductivity, high strength and flexibility. Because of certain additives, the material has a high resistance to corrosion and a melting point higher than Alumina. Zirconia is used in oxygen sensors as well as other technical applications.
