Insaco® does not produce or sell ceramic materials themselves. For this reason, we can offer advice without bias. Alumina is the most common technical ceramic and hence most readily available and usually lowest cost. Properties of alumina are exceptional in many ways when compared to conventional materials like steel. If the use conditions exceed these properties, other technical ceramics such as Silicon Carbide or Zirconia may be better choices even though less available or more difficult to fabricate. Please see our materials webpage for more information on the materials we frequently machine.
