95% Purity Brown Corundum Brown Fused Alumina f20 Sandblasting Material

1.Product introduction Brown fused alumina is made of high-quality bauxite, iron filings and anthracite as raw materials and is smelted in an electric arc furnace high temperature more than 2000 degrees. The brown corundum sectionsand is obtained by crushing the original slab of brown fused alumina and sieving after magnetic separation. Brown fused alumina with characteristics like:high purity,good crystalline liquidity,low coefficient of linear expansion,corrosion resistance,high temperature,high strength.It is suitable for grinding, polishing, sand blast,precision casting etc and used for refractory material. 2.
