95 Alumina Ceramic Custom Finishing


95%alumina industrial ceramic cup


95% alumina industrial ceramic cup is a type of high-performance ceramic material specifically designed for industrial applications. It is composed primarily of alumina (Al2O3), a highly durable and versatile ceramic compound known for its exceptional strength, hardness, and resistance to wear and corrosion.


Alumina industrial ceramic cups are widely used in various industries due to their exceptional properties. These cups are highly sought after for their durability, strength, and resistance to wear and corrosion. The high-performance ceramic material, primarily composed of alumina (Al2O3), ensures that these cups can withstand harsh industrial environments and continue to perform effectively. Their versatility allows them to be utilized in a wide range of applications, making them a popular choice among manufacturers and engineers. With their superior quality and reliability, alumina industrial ceramic cups play a crucial role in enhancing efficiency and productivity in industrial settings.


As an indispensable and important material, it has a broad application prospect in the fields of energy, aerospace, machinery, automobile, electronics and chemistry. These alumina ceramics are made into ceramic heating parts, alumina ceramic rods, ceramic shafts for pumps, ceramic seals for water pumps.

This ceramic has AL2O3 as the main component (AL2O3 mass fraction >45%). According to the content of AL2O3, it can be divided into 75% alumina ceramics, 95% alumina ceramics and 99% alumina ceramics.
