Product Description

Brown Aluminum Oxide for abrasive media & refractory raw materials with high quality


Brown Corundum / Brown Fused Alumina /Brown Fused Aluminum Oxide/ Brown Aluminum Oxide

Brown Aluminum Oxide is  made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard. High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.

The brown aluminum oxide abrasive has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion, and corrosion resistance. The practice of dozens of fire-proof production companies has verified that this product has the characteristics of no explosion, no chalking, and no cracking in the application process. In particular, it is much higher than the cost-effectiveness of traditional brown corundum, making it the best aggregate and filler for fused alumina refractories


Applications :

1.For Free grinding, such as glass industry.
2.For Friction products and abrasion resistance ground
3.For Resin or ceramic bonded abrasive,such as grinding wheels,cutting off wheels.
4.For Refractory Raw material, Wear-resistant and fire-proof products.
5.For Grinding and polishing ,such as gringing stone, Grinding block, flap disc.
6.For Coated abrasives,such as abrasive paper,abrasive cloth,abrasive belt.
7.For Producing mold of precision casting and Grinding, lapping and polishing media.

8.For Shot-blasting, such as for sandblasing oil piple and ship.
