The white corundum grits are used for the abrasive dress of the metal surface. The white corundum grits can also be referred to as the white corundum grits with a certain particle size.  White corundum is made up of mainly aluminum oxide, with its composition of (Al2O3). Most importantly, the excellent wear resistance, high hardness and good corrosion resistance, white corundum are frequently utilized in an assortment of industries.

Our white corundum grits particle size can be adjusted to different kinds of applications with big grit as well as small grit for specific purpose requirements. White corundum grit is available in different sizes. For instance, ultra-fine white corundum grits are usually applied in precision grinding processes where they are used to polish, turn, and eliminate tiny defects from the surfaces of materials and achieve good surface finish while coarser white corundum grits might be utilized in grinding and cutting processes where they are used for rapid material abrasion or rough machining.

On the whole, our white corundum grits are a type of only small-sized white corundum particles and are widely used for various industrial purposes to satisfy diverse requirements for dependence upon and in manufacturing.
