Applications of Spherical Aluminum Oxide Powder

High melting point, good thermal stability, high hardness, good wearability, high mechanical strength, high degree of electrical isolation, and corrosion resistance, it is widely used in the electronic and electric industry.

1. As a filler for rubber and resin, it can significantly improve the thermal conductivity of the mixture, reduce the expansion coefficient, and increase the strength of the mixture.

2. The spherical shape is conducive to the dispersion and sliding of the powder in the system. It can be evenly dispersed in the organic body and form the closest packing. It can obtain a mixture with high filling, low viscosity, and high thermal conductivity.

3. Wear on equipment such as kneaders, forming machines, and molds is greatly reduced, which can extend the life of the equipment.
