High strength zirconia dental ceramic stock block
- PRODUCT DETAIL
High strength zirconia dental ceramic stock block
Product features:
1.High strength and hardness
2. Good wear resistance
3. Insulation, corrosion resistance
4. High lubrication and low resistance
Since most of our products are custom-made, if the existing products do not meet your expectations, please provide relevant drawings and requirements, we can arrange the open mold production.
We mainly produce alumina ceramics, zirconia ceramics,and other ceramics.(If you dont know much baout the characteristics of material you can check the following form.)
