2250 ordm Melting Point Brown Fused Alumina Oxide for Sandblasting Industry Distributor
Product Description
Products description
Brown Fused Alumina(BFA) is made from calcined bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded and coated products. These grains are also used for shot blasting and as polishing media. Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.
Brown aluminum oxide
Brown corundum abrasive is produced by fusion of bauxite in an electric arc furnace at high temperatures.Brown fused aluminum oxide is of high hardness, toughness, self-sharpening, heat resistance and chemical stability, etc.
Brown fused aluminum oxide can be used in the manufacture of Bonded abrasives, Coated Abrasives,Vitrified/Resin grinding tool, and refractory, etc.
Brown aluminum oxide sizes :
For Abrasvies: F8-F220, F230-F1200. P8-P220 or any other sizes by customer's requirement.
For Refractories: 0-1mm, 1-3mm, 3-5mm, -200 mesh, 325 mesh or any other sizes by customer's requirement.
Advantages Of Brown Fused Alumina:
1.Hard material suitable for cutting(Mosh hardness 9)
2.Dense material for durable work(Bulk density between 1.4-2.2g/cm3)
3.High strength for cutting and polishing durably
4.Heat resistant(more than 2200ºC) proof of high temperature material loss or chemical reaction which may cause change on work piece surface

Applications

1. Abrasive blasting.Brown fused alumina as sandblasting abrasive hardness is moderate, high bulk density, no free silica, than the major, good toughness, is the ideal "green" type sandblasting material, widely used in aluminum, copper profiles glass, Washed jeans, precision molds and other fields;
2. Grinding.Brown Fused alumina is a grinding grade abrasive, used in the picture tube, optical glass, monocrystalline silicon,lenses, watches with glass, crystal glass, jade and other fields of free grinding, is widely used in the domestic high-level grinding materials;
3. Resin bond abrasive tools.Brown fused alumina with color suitable, good hardness, toughness, the appropriate particle type and edge retention, used in resin abrasive, the effect is ideal; Packaging & Shipping
