Product Characteristics of Aluminum Oxide Precision Ball

1.Dense without pores.
2.Large inventory of alumina balls.
3.Non standard sizes/diameters/specifications are available.
4.The toughness of alumina balls is relatively low.
5.Compared to silicon nitride balls, alumina balls are more suitable for use in situations with lower cost requirements.

Aluminum oxide ceramic balls are wear-resistant, heat-resistant, antioxidant, resistant to water, salt
solutions, and other chemical and acid corrosion. Additionally, it can maintain dimensional stability up
to 1100 ºC.
