The alumina balls' wear-resistance is higher than the common alumina balls'. When it is working, the ball won't pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.

High density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.

 Applications

Special bearings and valves, sealing elements (crushed balls), they are used in automotive 

industry (safety devices), aviation and aerospace industry, electronic industry, welding

 processes.
