AEM's nano high-purity alumina approved for Zürcher Frères' advanced ceramics

Advanced Engineered Materials (AEM) has announced that its nanoparticle high-purity alumina (HPA) has demonstrated improved mechanical performance in zirconia-alumina ceramics, following laboratory testing conducted by Swiss ceramics manufacturer Zürcher Frères SA.

According to AEM, the testing showed that ceramics produced using its nano HPA delivered higher hardness and fracture toughness compared with materials supplied by existing producers. Zürcher Frères described the performance of the ceramics as suitable for demanding applications requiring high mechanical strength and wear resistance.

Following the evaluation, AEM and Zürcher Frères have signed an ongoing cooperation agreement under which AEM will become the exclusive supplier of nanoparticle HPA for Zürcher Frères' zirconia-alumina ceramics production.

The agreement targets the global market for advanced zirconia-alumina ceramics, estimated at around 3,000 tonnes per annum. These materials are used in medical, dental, industrial and emerging ballistic applications.

Advanced Engineered Materials (AEM) produces high-purity alumina at its Cap-Chat facility in Quebec, Canada, and Zürcher Frères SA (ZFS) is a family-owned Swiss precision manufacturer with more than 69 years of experience in powder metallurgy and advanced materials.
