Brown fused alumina abrasive features micro-hardness of HV1800 - 2,200kg/mm'and is tougher than silicon carbide. lt is suitable for the normal grinding, cutting-off and loosegrain polishing of metal materials with high tensile strength, such as carbon steel, alloy steel.malleable cast iron and hard bronze. lt is also a very practical advanced refractory material.
Brown fused alumina also features high density, good wear resistance and highstrength. In the chemical industry, it can be used for variety of reaction vessels and pipesand chemical pumps. lt can also be used to manufacture mechanical components andvariety of dies, such as wire drawing die and tip of pencil lead extrusion die, and also beused for cutting and grinding tools, bullet-proof materials, seal rings, etc.
lt can also be used in thermal insulation materials, such as corundum lightweight brick.corundum hollow spheres and fiber products. With the maximum use temperature of 1,800 Cand the capability to resist high temperature and preserve heat, Brown Fused Alumina iswidely used in variety of high temperature furnaces and kins and furnace ceilings.
The brown fused alumina abrasive produced by our company is classified into class Pgrain and class F grain, with P grain as our major product. As one of the earliest researchersand manufacturers, our company has shown its excellent performance in this field andexported its products to many countries like Japan, Korea and US. Since different usershave diferent requirements, our company has also established corresponding standards tomeet the different requirements of our diverse customers.
