Brown Alox Manufacturer Brown Fused Alumina Supplier
Brown Alox Manufacturer Brown Fused Alumina Supplier
Brown Aluminum Oxide 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, the sieve is divided into various kinds. It’s very suitable for lapping preparation before solder surface mount component on circuit board.
