Zirconia – Alumina

Astro Met, Inc. manufactures zirconia material for advanced ceramic products. We use these materials to custom make products to meet your needs. We have more than 50 years of experience. We have worked with government agencies and private businesses. Representatives from our advanced ceramics division would be happy to discuss your specific needs and how our materials can meet them.

Product lines

We produce two types of zirconia materials. Our AmZirOx 86 is a zirconia yttria ceramic material. It is also known as Y-TZP. It is 95 per cent zirconia and 5 per cent yttria. Transformation toughening allows this material to absorb energy that would make most ceramics fail. It has a bulk density of 6.01g/cm3. Its flexural strength is 1000 MPa. It has a Vickers hardness of 1290. Its grains are 0.5 microns. It can be used in temperatures as high as 2400°C.

Our ZTA-96 zirconia toughened alumina combines the high strength and toughness of AmZirOx 86 with the wear resistance of our AmAIOx 68. ZTA-96 is 85 per cent alumina and 15 per cent zirconia. It is highly resistant to wear and corrosion, remains stable in high temperatures and has superior mechanical strength. It has a bulk density of 4.1g/cm3. Its flexural strength is 760 MPa. It has a Vickers hardness of 1750. It’s grains are 1.5 microns. It can be used in temperatures as high as 1650°C.

Industries served

Our zirconia and zirconia-alumina materials can be used in virtually every industry including: chemical processing, metal fabrication and automotive. Our material’s also used in the aerospace, food processing and medical industries. Our company has also served government agencies, including NASA.   

Manufacturing process

Our zirconia materials are ideal for meeting the most advanced ceramic needs. We can manufacture components in all shapes and sizes to precision tolerances and finishes.  Our advanced ceramics representatives would be happy to speak with you about how our products can meet your needs.


Our company also distributes Macor, a machinable glass ceramic, made by Corning Inc. This ceramic material is available in rod, bar and sheet stock shapes. It can also be used to make customized precision parts.
