Wear Resistant Alumina Ceramic Beads
My factory looking for distributors.
Advantages of wear-resistant alumina ceramic beads
1. The primary advantage of alumina ceramic beads is their extremely high hardness, demonstrating excellent wear resistance.
2. Alumina ceramic beads have excellent chemical stability. It exhibits good resistance in various chemical media, and is difficult to corrode whether it is acid, alkali, or organic solvents.
3. Alumina ceramic beads have a relatively low density and are lighter in weight. In practical applications, lighter weight means that the equipment can reduce its load and energy consumption during operation.
4. Alumina ceramic beads have excellent high temperature resistance, and their physical and chemical properties can still remain stable without problems such as softening, deformation, or performance degradation.
Applications of wear-resistant alumina ceramic beads
1. The high hardness of alumina ceramic beads makes it suitable for manufacturing cutting tools, grinding wheels, abrasives, drawing dies, extrusion molds, bearings, etc.
2. Alumina ceramic beads have the characteristics of high melting point and good corrosion resistance. It is also necessary for the production of furnace tubes, crucibles, fibers, thermocouple protection tubes, and other materials.
3. Alumina ceramic beads can also be made into pure metal and single crystal growth crucibles, human joints, artificial bones, sodium vapor lamps, microwave fairings, infrared windows, laser oscillation components, solar cell materials, and battery materials.
