Zirconia Machining and Grinding
|While the same design features common to alumina ceramics; blind holes, threads etc. are easily produced in Zirconia the grinding time required is about fifty percent more. The post-grinding surface finish is significantly better than a comparable feature in most aluminas.
Zirconia is much more dense, finer grain and stronger than alumina ceramic. The combination of these physical properties make Zirconia an excellent material choice when strength and wear resistance are required.
Zirconium Oxide ceramic has unique physical and chemical properties as you will see in the properties data sheet below.

Hot Isostatic Pressure (HIP)
The hot isostatic pressure process improves the physical structure and capability of ceramics by extracting impurities from the material via application of an inert gas. Once the parts are dense enough from the gas exposure, (usually processed in a chamber) they are suitable for medical applications, though all products are inspected before they are supplied to medical resources.
Injection Molding Technology
Injection molding is a process that involves producing parts (usually metals and ceramics) that are intricate in design, such as dental brackets. This process is executed by molding machines, and numerous devices are capable of being produced in a short time-frame. Injection molding is considered a good alternative to previous processing, as standard stamping and machining techniques of the past took more time and expense.
Alumina ceramic screws/nuts and bolts are used in applications where conventional metal or plastic components will not work. Ceramic nuts and bolts are strong, rigid, non-magnetic and operate at high temperature and in corrosive environments.
Alumina Properties sheet :
|Modulus of elasticity
|Highest application temperature
|Volume resistivity at 20°C
Product features :
High strength and no harm to healthy
2. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is
widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
4. High Strength not easy to break
5. Glazed and polished surface very nice looking
