Brown Fused Alumina are the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, and lapping and polishing processes. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important. 2.Brown fused alumina Applications Wet and dry blasting Grinding, lapping and polishing media Resin bonded grinding wheels and segments Resin bonded abrasive products Wear-resistant and fire-proof products Catalyst carrier Friction products 3.Size of Brown fused alumina #8, #10, #12, #16, #24, #30, #36, #40, #46, #54, #60, #70, #80, #90, #100, #120, #150, #180, #220-#600 4.Processing technic Air crush with the lowest bulk density, the shape of the material sharp Ball milling with the middle bulk density,the shape of the material between sharp and cube. Bamark with the highest bulk density,the shape of the material cube and circle. 5.Sieves using in processing Haixu's BFA is under the standard of FEPA,GB,JISR,ANSI. Generally,we use 5 sieves for sieving the material. And also can customize the sieving method for customers' special request.
