- Aluminum oxide abrasives
- Silica-based compounds
- Proprietary bonding materials
These materials are fired at extremely high temperatures to create a dense, hard, wear-resistant finishing media capable of maintaining its cutting characteristics throughout an extended service life.
Unlike natural abrasives, ceramic media is engineered with controlled density, hardness, and geometry, ensuring uniform finishing performance across every production batch.
Because of its controlled manufacturing process, ceramic media provides:
- Consistent cutting action
- Predictable finishing results
- Excellent dimensional stability
- Long operational life
