More info
Zirconia toughened alumina ball is a high-performance ceramic component made by integrating zirconia into an alumina matrix to enhance fracture toughness and mechanical strength. This composite structure offers excellent wear resistance, low thermal conductivity, and outstanding chemical stability. These balls are widely used in grinding media, mechanical bearings, valve systems, and high-load structural components exposed to corrosive or abrasive environments. Their dense microstructure ensures minimal wear and long service life, even under extreme operating conditions. Heeger Materials provides high-quality zirconia toughened alumina balls with reliable performance and customizable sizes.

Zirconia Toughened Alumina Ball Advantages
- Enhanced fracture toughness: Combines alumina’s hardness with zirconia’s toughness to resist cracking under stress.
- Superior wear resistance: Maintains shape and performance over long periods of abrasive use.
- Chemical inertness: Performs reliably in corrosive media like acids, alkalis, and solvents.
- Thermal stability: Suitable for high-temperature environments with minimal expansion or degradation.
- High density and uniformity: Ensures consistent grinding efficiency and mechanical balance.
Zirconia Toughened Alumina Ball Applications
- Grinding media: Widely used in ball mills for fine powder processing in ceramics, coatings, and electronics industries.
- Mechanical bearings: Serve in precision bearing systems where durability and low friction are required.
- Valve and pump components: Applied in check valves, seal balls, and pump seats in aggressive chemical environments.
- Wear-resistant structural parts: Function in mechanical systems exposed to repetitive friction and impact.
- Aerospace and energy sectors: Used in critical assemblies requiring strength, thermal resistance, and dimensional stability.
Zirconia Toughened Alumina Ball Packing
The Zirconia toughened alumina ball is securely packed in wooden crates or cartons, reinforced with cushioning materials to prevent movement during transit. This packaging approach ensures that the products remain intact and protected throughout the shipping process.
