Precision Ceramics offers a range of Zirconia-Alumina ceramic composite materials in different proportions between its main constituents covering a wide range of mechanical properties and intended uses.
Key properties
• Use temperatures up to 1500°C
• Chemical inertness • Wear resistance
• High bending strength
• High fracture toughness
• High hardness
• High performance Zirconia-Alumina ceramic composite
• Sintered to near theoretical density or HIP-ed for enhanced reliability
• Excellent balance between bending strength, hardness and fracture toughness.
• Increased tolerance to hydrothermal ageing
Applications
• High pressure equipment - ball valve balls and seats
• Rollers and guides for metal forming
• Thread and wire guides
Alumina-Zirconia (ATZ) and Zirconia-Alumina (ZTA) high performance ceramic composites are unique ceramic materials by way of exhibiting a combination of high hardness, strength, wear and corrosion resistance characteristic to their Alumina component while still maintaining reasonably high fracture toughness specific to its Zirconia component.
• Metal extrusion dies
• Deep well down-hole valves and seats
• Shaft bearings/bushings
