White Fused Alumina For Polishing

Moh's hardness 9.0 Bulk density 1.75-1.95g/cm³ Real density 3.95g/cm³ Melting point 2250 Maximum service temperature 1900

White Fused Alumina polishing was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

Hot sale White fused alumina/corundum/WA for polishing and grinding White fused alumian/corundum is an artificial corundum abrasive, the main component of aluminum oxide (Al2O3), and contains a small amount of iron oxide, silicon oxide, etc., the color was white. White corundum high quality alumina powder as raw material, refined crystalline and fused into, there are dense texture, high hardness, high temperature, acid corrosion, thermal stability properties. particles cusp form for use in the manufacture of ceramics, resin bonded abrasives and grinding, polishing, blasting, precision casting, can also be used to manufacture advanced refractory.

White Fused Aluminium Oxide (WFA)� is widely used for Abrasive Tools, Sandblasting, Polishing, Surface Preparation. Our WFA is a hard, dense and iron-free material with highest purity, hence is an ideal abrasive material. It also has above 95% Al2O3 content, high degree of whiteness, extreme hardness and a wide range of precise grit sizes.

Brown fused alumina polishing Brown aluminum oxide crystals is made of bauxite/anthracite coal, and smelted in electric-arc furnace of high temperature more than 2000degrees.Abrasives tools made by brown fused alumina are suitable for metal with high tensile (like:steel, malleable iron, bronze etc).and suitable for grinding, polishing, blasting, precision casting etc.Brown aluminum oxide crystal is also used for refractory material. Brown aluminum oxide crystals with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength.
