Brown corundum is made of bauxite and coke (anthracite) as the main raw materials. It is smelted at high temperature in an electric arc furnace. The abrasive tools made of it are suitable for grinding metals with high tensile strength, such as various general steels , Malleable cast iron, hard bronze, etc.

White corundum is a kind of artificial abrasive. The content of aluminum oxide (Al2O3) is more than 99%, and contains a small amount of iron oxide, silicon oxide and other ingredients, which is white.

The main raw material of black corundum is aluminum oxide (AI2O3) with a content of 70% to 80%, containing more impurities such as silicon oxide and titanium oxide, and it is a black corundum. It is a new type of environmentally friendly material.

Silicon carbide abrasive, also known as moissanite, can also be called emery or refractory sand. It is a man-made substance. It is made by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips in a resistance furnace.

Walnut shell filter material is a water treatment filter material that uses high-quality pecan shells as raw materials, which is crushed, polished, steamed, washed, and treated with medicines, and then screened and processed twice.
