Brown Aluminum Oxide Powder 240mesh for PCB Polishing

Description:
Brown fused alumina is made of high-quality bauxite, anthracite and iron filings. It is cooled and smelted in a high temperature by more than 2000 degrees in an electric arc. It is crushed and shaped by a jaw crusher and a ball mill. After magnetic separation, then sieve separated to get various kinds. Its compact texture, high hardness, suitable for the manufacture of ceramics, grinding of high tensile metal and grinding, polishing, sandblasting media, precision casting, etc., can also be used to produce advanced refractory materials.

Application:
Brown fused alumina is widely used as a raw material in many industries：
1. Laminates, coatings, lapping, polishing
2. Polishing
3. Buffing and compounds for ferrous and non-ferrous metal, ceramic, and stone.
4. Wear resistance applications
