| Product exhibition: Type -- Brown Fused Alumina (A) |
 |
| Brown fused alumina is fused and crystallized under high temperature from a mixture of bauxite and other raw materials. It is characterized by its high hardness , good toughness and sharp shape in size. Abrasives tools made of it are suitable for grinding metals of high-ten-sile strength such as: carbon steel, general purpose alloy steel, annealed malleable iron and hard bronze , etc. It also can be used as refractory materials. |
