Aluminum Oxide (AO)

AO is formed by combining bauxite and other materials by firing them in an electric furnace. The resultant mass is then crushed, and the pieces sifted through successively finer screens to assign a grit size (CAMI grading). When crushed, the resulting pieces are naturally pyramidal in shape. Due to the shape and the strength of the materials used in its making, AO is a very durable grain. The grain is worn down during use, sanding finer the longer it's used. Users take advantage of this characteristic by using the belts on more than one machine or application. For instance, if you have two wide belt machines doing intermediate and finish sanding, respectively, you may use a 120 belt on the first machine to do your intermediate sanding. When the cut for that application is no longer as sharp, the belt can be used for 150-grit application.

AO is very tough and durable, as stated above, and is used on bare wood, most metals (especially the steels), leather, and a wide variety of other materials. It is a great general-purpose grain and probably the most common grain seen today.
