Single Crystal Aluminum Oxide

Single Crystal Aluminum Oxide (Mono Crystal Aluminum oxide) is produced in a new technical process. Its color is light blue and its bulk density is stable (F16: 1.89 g/cm3; F180: 1.65 g/cm3). Products of various particles are formed naturally, instead of mechanical smashing. it has the advantages of good multi prism cutting edge and high hardness and toughness, strong grinding ability, and low grinding heat.

It can be used in vitrified, resin-bonded and rubber-bonded wheels. The grinding wheels made which it are rusty spot free and no shrinking. The grinding wheels’color is light blue when the fired temperature is between 300℃ and 1280℃. The color will be brown when the firing temperature>1280℃, but the brown color does not influence the function of the grinding wheel. It is good for grinding and cutting high hardness, high toughness such as high vanadium high speed steel, austenitic stainless steel, heat-resistant alloy steel, titanium alloy steel, especially for the grinding and processing of dry mill and burned workpiece easily.
