Zirconia Bead

AZAlumina Toughened Zirconia Bead

The AZ Bead, (DiaBeadsTM), has a medium density (≥5.1), between the densities of zirconia (≥6.0) and zirconium silicate bead (≥4.0). As a result, where the motor power and cooling capacity of the grinding machine is sufficient, this bead is suitable for higher efficiency grinding than the zirconium silicate bead.
