Product Description
Low Thermal Conductivity Zirconia Ceramic Bullet Rod
Zirconia ceramics are widely used in structural applications due to their exceptional combination of high toughness, flexural strength up to 800 MPa, and superior wear resistance. These advanced ceramics feature excellent thermal insulation properties with a thermal conductivity of 2.5 W/(m·K) and a thermal expansion coefficient closely matching that of steel.
Product Applications
- Y-TZP grinding balls and dispersion media
- Nozzles, ball valve seats, and zirconia molds
- Micro fan shafts, fiber pins, and fiber sleeves
- Wire drawing dies and cutting tools
- Wear-resistant tools and industrial components
- Ball bearings and precision mechanical parts
