99.9% Al2O3 White Fused Alumina for Sandblasting Media
Production process:
White fused alumina in industrial aluminum oxide powder as raw material, to the arc by high temperature above 2000 degrees of melting cooling made by crushing, plastic, magnetic separation to iron.
Properties: High temperature resistance, corrosion resistance, high hardness, high strength, wear resistance, good crystallization, low coefficient of expansion. Bulk density, 3.5g/cm3, Knoop hardness, 2000 - 2200 Kg/mm2, . Mohs hardness, 9.0. Color white, dark blue, after calcination. The highest temperature is 1900, melting point 2250. With its dense texture, high hardness, sharp particle formation. Can sieve into a variety of size.
Use:
1 white fused alumina is suitable for a variety of high-end product, process or hardware products beautify the surface treatment, surface white after blasting without any impurities, removed from the cleaning trouble. Fine white corundum used as polishing grinding head. Can also be used for a variety of products additives.
2 beautify processing: All kinds of gold, K gold jewelry, extinction or mist precious metal products processing, crystal, glass, corrugated, acrylic and other non-metallic fog face processing and can make the machined surface metallic luster.
Also suitable for the manufacture of ceramics, resin bonded abrasives and grinding, polishing, sandblasting, precision casting (casting special corundum), also can be used in the manufacture of high-grade refractory materials.
