Description
Alumina (Al₂O₃) ceramic balls are known for their exceptional corrosion resistance, high-temperature stability, and hardness. These characteristics make alumina balls one of the most versatile choices for industrial applications such as grinding, chemical processing, and high-temperature environments. With a density of approximately 3.9 g/cm³, alumina ceramic balls provide excellent performance and durability for demanding tasks.
Key Features
- Corrosion Resistance: Alumina balls are resistant to most acids, alkalis, and salts, making them ideal for use in harsh chemical environments.
- High-Temperature Stability: Suitable for high-temperature applications, alumina ceramic balls retain their integrity even in extreme heat, making them perfect for chemical processing and furnaces.
- Hardness and Wear Resistance: With their high hardness, these ceramic balls offer superior wear resistance, ensuring a longer lifespan and reducing maintenance needs.
- Non-reactive: The chemical inertness of alumina makes these balls suitable for use in industries where contamination must be avoided, such as food and pharmaceuticals.
- Water Absorption: Low water absorption (≤ 5%) helps maintain performance in environments where moisture exposure is a concern.
