ZTA ceramic parts
Zirconia Toughened Alumina (ZTA) serves as the ideal intermediate material solution between zirconia and alumina, this composite material combines the advantages of both materials, offers superior mechanical strength and abrasion resistance. This cermaic material is a specialized alumina that is stronger and tougher than ordinary alumina ceramic, and provides high thermal shock resistance, but cost less than zirconia.
