1.Different raw materials: the raw material of brown corundum is bauxite, in addition to anthracite and iron filings. The raw material of white corundum is aluminum oxide powder.
2.Different properties: brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion, corrosion resistance. White corundum has the characteristics of high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance and stable thermal performance. In comparison, white corundum hardness is higher than brown corundum.
3.Different ingredients: although both brown and white corundum contain alumina, white corundum is high in alumina,
4.Different colors: Because the alumina content of white corundum is higher than that of brown corundum, the color of white corundum is white, and brown corundum is brown black.
5. Different production: white corundum is made of alumina powder (the same raw material as electrolytic aluminum), while brown corundum is made of calcined bauxite.
6.White corundum has strong cutting force, used to remove metal or non-metal burr, batch front burr, etc. It has the function of polishing parts surface, brown corundum used to remove stainless steel, carbon steel, aluminum alloy and other hardware parts surface burr
7. The use of different objects: white corundum is used by some high-end users, because it is better cutting strength, polishing effect is very good, mostly used for carbon steel, alloy steel, malleable iron, hard bronze and so on, and brown corundum is widely used in the market, but also the market dosage is relatively large, mostly used for fire steel, high-speed steel, high carbon steel and so on.
White corundum has strong cutting force, used to remove metal or non-metal burr, batch front burr, etc. It has the function of polishing parts surface, brown corundum used to remove stainless steel, carbon steel, aluminum alloy and other hardware parts surface burr. Brown corundum does not grind as fine and bright as white corundum.
