Product Description
P grit Brown Fused Alumina for making abrasive paper,belt, brick, cloth from China
Brown Corundum / Brown Fused Alumina /Brown Fused Aluminum Oxide/ Brown Aluminum Oxide/Brown Fused Carborundum
Description:
Brown fused alumina is fused and crystallized under high temperature from a mixture of calcined bauxite,coke(anthracite),scrap iron and other raw materials.
Brown fused aluminum oxide is a tough, hard material (Mohs hardness 9) with high strength, excellent wear and corrosion resistance and good thermal conductivity.

Applications :
1. Used for refractory materials, castable refractory bricks, etc.
2.sand blasting - BFA as abrasive,hardness is moderate, high bulk density, no free silica, large specific gravity, good toughness, is an ideal "environmental" type sand blasting material, widely used in aluminum profiles, copper profile glass, washed denim Precision molds and other fields
3. grinding grade abrasive—applied to picture tube, optical glass, monocrystalline silicon. Lens. watch glass.crystal glass.jade. etc.,
4, resin grinding —with suitable color.hardness. Toughness. particle cross-section type and edge retention.it is applied to resin abrasives with ideal effect;
5, coated abrasives — sandpaper.gauze
6, functional fillers— mainly used in automotive brakes. special tires. special construction products.etc.
can be used as a highway pavement. Aircraft runway. Terminal. Parking lot. Industrial floor. Sports ground and other wear-resistant materials;
7. Filter medium—It is a new application field of abrasive. use granular abrasive as the bottom medium of filter bed to purify drinking water or waste water. ;used for non-ferrous metal beneficiation: oil drilling mud weighting agent
8.Hydraulic cutting—It is a cutting medium, It relies on high-pressure hydraulic jet for basic cutting. It is applied to the cutting of petroleum (natural gas) pipelines, steel and other components. It is a new, environmentally friendly and safe cutting method.
