ALU-MIC A,B,C, aluminas are unmilled precursors of the ALU-MIC 1000 powders. These standard type high purity aluminas have been used for many years in metallurgical polishing, less stringent optical polishing, or wherever a totally scrach free surface is not indicated. They have been identified by the industry designations of B (0.05), A (0.3) C (1.0) aluminas.
ALU-MIC aluminas are characterized by their ability to break down during the polishing operations to produce very nicely polished surfaces, but with surfaces roughness coarser than ALU-MIC 1000 aluminas procedure.
