Frequently Asked Questions

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.

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 requiring precision and durability.
