FAQ
What are alumina ceramic balls made of?
They are made from aluminium oxide (Al₂O₃), a high-purity ceramic material known for its hardness and wear resistance.
What are the key properties of alumina ceramic balls?
High hardness, excellent wear resistance, chemical stability, high-temperature resistance (up to 1600°C), and electrical insulation.
What are alumina ceramic balls used for?
They are used as grinding media, bearing components, valve balls, and in applications requiring wear resistance and chemical inertness.
Why choose alumina balls over steel or other ceramics?
They offer superior wear resistance, chemical stability, and are lighter than steel, making them ideal for specific applications.
What sizes are available for alumina ceramic balls?
Sizes typically range from 1mm to several inches, depending on the application.
