High Strength Zirconia Ceramic Needle Wear Resisting For Mechanical Industry
Yixing kamtai made high strength zirconia ceramic needle
1. Description
Zirconia ceramic has the advantages of super hardness, high wear-resisting,good corrosion resistance and electric insulation,resistant acid-base,high intensity,thermostable,high temperature tolerance,good insulation,high strength,precision process,high mechanical strength,good chemical stability.Good smoothness, mechanical seal good, polishing surface and so on.
Components made from this material are more expensive than components made of alumina ceramics. Zirconium oxide ceramics are used among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.
Magnesia-partially-stabilised zirconia (MgO-PSZ) and yttria-partially stabilised zirconia (Y-TZP) in particular offer an outstanding resistance to mechanical shocks as well as to flexural load, because of their high fracture toughness and relative “ elasticity ”. These two zirconias are advanced ceramics of choice for severe mechanical applications.
2. Main Features
1. High strength, high fracture toughness and high hardness
2. Excellent abrasion resistance
3. The elastic modulus and thermal expansion coefficient are similar to the metal
4. Low thermal conductivity
