Alumina powder is made of liquid aluminum hydroxide by extrusion solidification,
Alumina powder is made of liquid aluminum hydroxide by extrusion solidification, which contains a variety of elements, and the content is high, the overall density is higher than the general aluminum powder. The surface of alumina powder is closer to the ideal surface than that of other metal powders, so it has good exhaust performance. The particle size of alumina powder is generally 90-100 microns, has good suspension, no load charge, can be oxidized at low temperatures, and has excellent electromagnetic characteristics.
