What does it mean BFA F060? BFA,in the abrasive field,it means Brown Fused Alumina, is a type of electrofused artificial corundum made by process fusing bauxite and other elements in electric arc furnaces. Fusion under very high temperature makes the materials in the furnaces liquid materials. The materials are then cooled down and become crystal forms

Natural emery, also called garnet sand, is a natural abrasive, which is directly mined from mines. The raw materials are screened and classified into abrasive materials without manual smelting. The processing time is short, the efficiency is high, the price is low, and it can make up for the short life. insufficient. It is widely
Which kind of emery sand can be used for blasting PCB(Printed Circuit Board)? In China,white fused alumina,brown fused alumina,black silicon carbide and green silicon carbide are all called emery sand. But usually brown fused alumina is used mostly in blasting PCB.
