1. Description:
Brown aluminium oxide/brown fused alumina is fused and crystallized under high temperature from a mixture
of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and
shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as:
carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc. It also can be used as
refractory materials.
2. Application:
♦Suitable for grinding high-speed,high carbon steel
♦High-grade refractory materials
♦Abrasives tool
♦Grinding and polishing
♦Ceramics
♦LED
♦Sandblasting
♦Aviation
