HIGH PURITY ALUMINUM OXIDE (ALUMINA) POWDERACW - CALCINED ALUMINUM OXIDE POWDER. ACW is a high purity (>99%) alumina powder. Each particle is a discrete crystal of alumina, with asmooth surface distinctive platelet shape with a 5:1 aspect ratio. Each ACW particle has highstrength and high resistance to fracture.APPLICATIONS:ACW is ideal for surface finishing products such as precision optics, piezo-electronics, bearings, semi-conductor materials, quartz, Germanium, stainless and hardened steels, ferrous & non-ferrousmetals, and many others.
