- Optimized for Pressing: Specifically designed for Isostatic Pressing and Dry Pressing methods, ensuring excellent formability and consistency.
- Superior Flowability: The spherical granulation (60-200 mesh) provides excellent flow characteristics, enabling fast and uniform die filling for high-volume production.
- High Green Strength: Results in robust, handleable green bodies that resist cracking or damage before sintering, reducing waste and improving yield.
- High Final Density: Achieves exceptional fired density (up to 3.80 g/cm³), leading to ceramics with excellent mechanical strength, wear resistance, and electrical insulation.
- Uniform Shrinkage: Predictable and consistent sintering shrinkage allows for precise dimensional control in the final machined component.
This versatile alumina ceramic powder is ideally suited for manufacturing a wide range of advanced ceramic components, including:
- Electronic Ceramics: Substrates, insulators, spark plug cores, and other components requiring high purity and reliable performance.
- Structural Ceramics: Wear-resistant parts, seals, nozzles, cutting tools, and other mechanical components that demand high strength and durability.
We provide high-purity, consistently graded alumina powders that are critical for producing reliable and high-performance ceramic products. Our CP-99 grade is particularly recommended for the most demanding applications where maximum density, purity, and material performance are required.
