Brown Fused Alumina is electrically fused in an arc furnace from a mixture of bauxite, coke (anthracite) which is as the main raw materials at high temperature. Its chemical composition contains Al2O3, a small amount of TiO2, SiO2, and Fe2O3, etc, micro hardness: 1800-2200kg/mm², toughness is higher than silicon carbide. The product which made of Brown Fused Alumina is suitable for grinding metal with high-tensile strength such as steel, annealed malleable iron and hard bronze etc. Brown Fused Alumina can also be used for making high-standard refractory products.

Agglomerate Abrasive is a new type abrasive. It is characterized by high precision, good heat dissipation, self-sharpening and excellent efficiency. The product can meet various requirements for grinding, wiredrawing, polishing, etc. Its application fields are expanding widely.

Agglomerate Abrasive

Magnetic abrasive is one kind of magnetic nanoparticle based on magnetic-sensing material, composed of one or many abrasives, heat dissipation and lubrication materials. The magnetic-abrasive finishing is a new type of processing method assisted by magnetic field used for polishing workpiece surface. Magnetic abrasive can process workpiece with various shapes such as hole, cavity, groove, internal clearance with little gap, etc.

Magnetic Abrasive

Spherical nanometer ceramic corundum abrasive is spherical particle made of alumina oxide. It is characterized by small crystal, high hardness and toughness, good fluidity. It is easier to keep shape of abrasive particle, which can improve accuracy and stability during grinding. It is mainly used for grinding precision components.
