Alumina Ceramics:
In various fields such as industry and different industries, the demand for ceramic rods is different. The main considerations are: wear resistance, heat insulation, high temperature resistance, corrosion resistance and lubrication of ceramic rods! The main materials of ceramic rods are mainly Zirconia Ceramics and alumina ceramics. What is the difference between these two types of ceramic rods? Zirconia Ceramic Rods: Zirconia Ceramic rods have better wear resistance, high hardness and resistance to pressure. The management is strong and the density is higher than 6.0. The advantage of the large Zirconia Ceramic Rod is that its toughness is very good! The machining of the semi-sintered ceramics is to minimize the machining allowance of the completely sintered ceramics, thereby improving the processing efficiency and reducing the processing cost. Grinding and polishing processing is a super-finishing method that uses a free abrasive to finely remove the surface material to be processed to achieve a processing effect. In the ultra-finishing and finishing of ceramic materials, especially in the precision machining of ceramic balls for ceramic bearings, grinding and polishing have an irreplaceable position.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
