3.175mm 3.969mm Precision ZrO2 Ceramic Ball Zirconia Beads for Alloy Wheels
Zirconia Ball : name as yttrium stabilized zirconia beads, 95 zirconia ceramic bead, zirconium bead, ultra-fine grinding medium, zirconia microsphere, zirconia grinding ball,zirconia grinding media for grinding Materials for grinding and dispersing: structural ceramics, electronics ceramics, refractory ceramics, magnetic material, metallurgy, medicine, food, cosmetics, textiles, printing and dyeing, pigment and other industries.
It has a pearl luster and smooth working sphere, dense internal structure, super high densiry , strong compressive strength and super high wear resistance, and is a high-end product in abrasive media. However, this product has a high requirement for the use of the hardness of the memory material in the grinding machine.
Features of Zirconia Ball
1. Preventing material from contamination because of its extreme low wear rate
2. High grinding efferency
3.Lower total costs due to longer using life
