Semi-friable Aluminum oxide is produced by aluminum oxide, then melt in an electric furnance at high temperature of more than 2000℃. Because it not only has reasonable hardness, but also has reasonable brittleness which is between white fused aluminum oxide and brown fused aluminum oxide, it is named Semi-friable Aluminum oxide.
As a new kind of abrasive grains, it has its unique advantages, such as excellent self-sharpening, good toughness, excellent heat resistance, semi-friable can be applied to the manufacture of vitrified abrasives, resinoid abrasives, coated abrasives. The workpieces processed by them has a better appearance effect, better durability and higher machining efficiency than other abrasive grains.
