BALLS – Synthetic
Aluminum Oxide

The material characteristics of Aluminum Oxide Balls are comparable to Synthetic Ruby and Sapphire Balls. However, the polycrystalline structure leads to a slightly reduced density and increased stability during changes in temperature. Aluminum Oxide Balls are well suited to abrasive operational conditions. Their excellent biocompatibility has made them a standard component for endo-prosthesis joints. They are off-white in color. Larger sizes are available by special order.

Grade: 10.
Sphericity: 0.00001.
Specific Gravity: 3.95.

Should you require a ceramic ball with unusually high fracture toughness and flexural strength, coupled with a near-to-steel low modulus of elasticity, zirconium oxide balls are available.
