ALU-MIC A, B, C, series alumina are the un-milled precursors of ALU-MIC 1000 powders. These standard type high purity alumina have been used for many years in metallurgical polishing, less stringent optical polishing, or wherever a totally scratch free surface is not indicated. They have been identified by the industry designation of B (0.5), A (0.3) and C (1.0) alumina. ALUM-MIC A, B, C alumina are characterized by their ability to break down during the polishing operations very nicely polished surfaces, but with surface roughness coarser tan the ALU-MIC 1000 alumina produce.
ALU-MIC 1000 series alumina are derived from calcination of high alum in precisely controlled electric furnaces. Unlike most lapping and polishing alumina, ALU-MIC 1000 agglomerate free alumina are jet milled to maintained high purity and prevent extraneous material from contaminating the powders. Each lot of alumina is thoroughly blended to maintain consistent quality.
ALU-MIC 1000 series alumina are perfect for most infrared materials, stainless steel, non-ferrous and exotic metals, electro-optic and laser crystals, ophthalmic lenses and many more applications.
