Zirconia Toughened Alumina Ceramics

ZTA (Zirconia Toughened Alumina) is a composite material made from alumina and zirconia. It combines the outstanding characteristics of both materials.

Compared to conventional alumina, ZTA possesses superior hardness, higher flexural strength, and similar density. Compared to conventional zirconia, it possesses a lower coefficient of linear thermal expansion and higher thermal conductivity.
By leveraging these features, ZTA has been widely adopted in milling parts and wear-resistant parts that require cooling.
