Alumina Ceramic Beads Product Features
My factory looking for distributors.
Advantages of Alumina Ceramic Multi Bores Beads
1. Alumina ceramic Multi Bores beads have excellent wear resistance and can maintain shape and size stability for a long time in high-speed grinding, polishing and other applications, making them less prone to wear and greatly improving grinding efficiency and quality.
2. Alumina ceramic Multi Bores beads has high compressive strength and can be widely used in situations where high pressure and impact forces are required.
3. It have excellent high-temperature resistance and can maintain stable physical and chemical properties in high-temperature environments.
4. Compared to some metal materials, the density of Alumina ceramic multi bores beads is relatively low, but their strength is high.
5. Under high temperature and oxidizing atmosphere, a dense layer of alumina film will form on the surface of alumina ceramic beads, which can effectively prevent further inward diffusion of oxygen and thus have good antioxidant properties.
Applications of Alumina Ceramic Multi Bores Beads
1. The high hardness of Alumina Ceramic Multi Bores Beads makes it suitable for manufacturing cutting tools, grinding wheels, abrasives, drawing dies, extrusion molds, bearings, etc.
2. Alumina Ceramic Multi Bores Beads are applied in fields such as aerospace and electronics, which can reduce equipment weight while ensuring performance.
3. It can maintain stability in various chemical environments and can be used for processes such as grinding and dispersing corrosive media.
4. Alumina ceramic beads can be used for a long time in high-temperature oxidation environments, such as in high-temperature burners, heat treatment furnaces, and other equipment as high-temperature resistant and anti-oxidation components.
5. The surface of alumina ceramic beads can achieve high smoothness, which enables it to reduce frictional resistance in applications such as fluid transportation and rolling bearings.
