Al-30	99.75	α	9	8.0-9.0	0.25	3.0	3

Product features: fine particles, no agglomeration, narrow particle size distribution and high purity.
Advantage: machining accuracy in Å will not cause scratches by reason of agglomeration, and the close tolerance control of particle will keep danger away from unwanted impurities.   
With fast and high-quality processing, it reduces scratchescaused by a wide distribution of particles.
Main applications: infrared materials (Ge, ZnS, ZnSe) contact lenses, precision alloy (tungsten-aluminum-copper alloy wiring materials and thin-film materials in intermediate layer of integrated circuit), tiny precision ball bearing, optical steel mold, speculum, electron optics, laser crystal, natural stone, artificial gemstones and other materials. 

Zirconium oxidepolishing solution, as a kind of zirconia polishing powder and special suspending agent made through precise control of particle size, is applied to the mass production of soft lenses jointly with LP polishing pad, felt or synthetic leather with features of long service life and great polishing effect.
