Brown corundum (aluminum oxide, corundum grit) is suitable for a variety of dry and wet processing processes. It can grind any rough surface of the workpiece finely and is one of the most economical abrasives. This sharp and angular synthetic abrasive has a hardness second only to diamond and is particularly suitable for use when there are strict requirements for iron contamination. It is used for the roughest cutting and can also be made into pebbles to process precision-sized workpieces to achieve extremely low roughness. Due to its high density, sharp and angular structure, it is one of the fastest cutting abrasives currently available.
Brown corundum (corundum grit) is made by electrofusion of high-quality bauxite ore, while high-quality aluminates are used to produce powdered corundum and white corundum. Their natural crystal structure makes them hard and fast in cutting performance. They are also often used as raw materials for bonded and coated abrasives.
Brown corundum (corundum grit) can be recycled many times, the number of cycles depends on the material grade and the specific process, and can be used with most standard abrasive sandblasting equipment.
