Often employed for sandblasting and sanding discs, zirconia alumina, is the crystallized result of aluminum oxide and zirconium dioxide. Other weights (S,T,M) are seldom used, only for specific applications and products.

The relative hardness of an abrasive compared to the material being worked on (harder abrasives will cut deeper faster), Adhesion between grains (determines how quickly grains are lost), Loading (worn abrasives can reduce cutting efficiency), Contact force (greater force will result in faster abrasion), Use of lubricant, coolant, or metalworking fluid (can help to carry away sanding debri to prevent friction and reduce heat).

Before we discuss each of these grains, its important to consider why these characteristics matter.

Premium abrasive products typically feature cloth or other synthetic backings. Critical aspects of narrowing down your decision include: Grit level is the most vital when choosing your abrasive grain, as it describes the density of the abrasive and its strength against other materials.

Open coat abrasives work best with softer woods like cedar and pine. Ceramic is friable, continuously delivering a sharp cutting surface, increasing the already impressive longevity of the product. Aluminum oxide is a chemical compound of aluminum and oxygen formed by fusion and then broken down and sorted by grit size through a series of mesh screens (see this video for an example). For abrasive wheels, the grains are then bonded to a wheel using one of six types of bonds: For coated abrasive products, the grains are bonded to a backing using resins, glues, and/or varnish. We are proud to offer these products direct to consumers with our Red Label Line. Brown, or semi-friable, aluminum oxide is the most common type of aluminum oxide, because of its versatility.
