Zirconia Toughened Alumina Rod/Bar Description

Zirconia toughened alumina rod/bar is made from a composite ceramic that combines the hardness and thermal stability of alumina with the added fracture toughness of zirconia. This combination significantly improves resistance to cracking and wear, making it suitable for demanding applications such as precision shafts, insulating rods, support pins, and structural bars exposed to high temperatures or corrosive environments. The fine microstructure ensures reliable long-term performance under both mechanical load and thermal cycling. 

Zirconia Toughened Alumina Rod/Bar Features

  • Enhanced Toughness: The addition of zirconia improves fracture resistance, reducing the risk of cracking.
  • High Hardness: Maintains excellent surface hardness, ideal for wear-resistant applications.
  • Thermal Stability: Performs reliably at elevated temperatures with low thermal deformation.
  • Chemical Resistance: Withstands corrosion in harsh chemical environments.
  • Fine Microstructure: Ensures consistent strength and durability across thermal cycles.

Zirconia Toughened Alumina Rod/Bar Applications

  • Wear-Resistant Shafts: Used in high-friction systems where durability and precision are critical.
  • High-Temperature Insulators: Function as electrical or thermal insulation in furnaces and reactors.
  • Support Pins and Guides: Serves as stable structural elements in mechanical assemblies.
  • Chemical Processing Equipment: Performs well in corrosive environments with acids or molten materials.
  • Precision Mechanical Parts: Applied in aerospace, semiconductor, and analytical equipment requiring dimensional stability.

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

Zirconia Toughened Alumina Ceramic Machining

CNC machining for ceramics HM 3

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.
