Zirconia Toughened Alumina Block Description
Zirconia toughened alumina block combines the hardness and chemical stability of alumina with the enhanced fracture toughness of zirconia, resulting in a material that resists cracking and wear under demanding mechanical and thermal conditions. This block maintains excellent dimensional stability at high temperatures and performs reliably in corrosive environments, making it suitable for use in structural parts, wear plates, insulation supports, and high-load components. Its fine microstructure ensures long service life and consistent performance under cyclic stress.

Zirconia Toughened Alumina Material Properties
Zirconia Toughened Alumina Material Grades
CeramAlloy ZTA is a high performance ceramic composite and a unique ceramic material by way of exhibiting a combination of high hardness, strength, wear and corrosion resistance resulting from its Alumina content, while still maintaining reasonably high fracture toughness resulting from its Zirconia content.
Applications:
- High pressure equipment – ball valve balls and seats
- Rollers and guides for metal forming
- Thread and wire guides
- Deep well down-hole valves and seats
- Shaft bearings/bushings
Ultra Hard is a high performance ceramic composite and a unique ceramic material by way of exhibiting a combination of high hardness, strength, wear and corrosion resistance resulting from its Alumina content, while still maintaining reasonably high fracture toughness resulting from its Zirconia content.
Applications:
- High pressure equipment – ball valve balls and seats – particularly suitable for high flow/abrasive fluids
- Focusing nozzles for abrasive media
- Ultra high pressure pumping elements
- Deep well down-hole valves and seats
- Rollers and guides for metal forming
- Thread and wire guides
- Metal extrusion dies
Zirconia Toughened Alumina Ceramic Machining
Zirconia Toughened Alumina (ZTA) is a high-performance composite material that enhances toughness and strength by incorporating zirconia (ZrO₂) into alumina (Al₂O₃). Machining this material requires addressing its high hardness and brittleness. Key machining aspects include:
- Cutting: Utilizes diamond tools or laser cutting for precision and edge integrity.
- Grinding: Employs precision grinding to control surface roughness and dimensional tolerances.
- Drilling: Uses ultrasonic or diamond drills for micro-holes, ideal for electronic applications.
- Surface Finishing: Polishing or coating improves wear resistance and aesthetics.
ZTA machining is widely applied in precision component manufacturing, such as electronic substrates and medical implants.
Zirconia Toughened Alumina Ceramic Packaging
Zirconia Toughened Alumina Ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
