Aluminium oxide

Commonly called “polishing alumina”, the chemical symbol Al2O3, they comprise several families: purified aluminas, melted aluminas, calcinated aluminas, sub-micron aluminas. Their choice is defined according to the criteria of results and economic requirements. Grain sizes between 0.03 microns and 200 microns.

Silicon carbide

Silicon carbide is a chemically pure body, the chemical symbol SiC. The grains are coloured grey, green or black. The grain F1500 used for very specific super finishing is coloured grey. The AQUA LAM® silicon carbide undergoes a special treatment, as well as a separation under a strong magnetic intensity to ensure dust removal and a maximum cleanliness. AQUA LAM® proposes all the FEPA F grain sizes useful in lapping; they are scaled from F60 (250 microns) to F1200 (3 microns).

Cerium oxide

The chemical symbol CeO2. Used in superfinishing mainly for the polishing of glass (example BK7, 520 knoops), cerium oxide lowers the roughness by a chemical and mechanical action. Selected according to its maximum polishing action, the AQUA LAM® cerium oxide is present in grain sizes of 3 to 0.5 microns (other grain sizes on request).

Boron carbide

The chemical symbol B4C. Micronized with the highest rigour, the AQUA LAM® boron carbide is ideal for all lapping and polishing applications requiring a high-performance ultra abrasive. Average hardness 2900 to 3500 knoops. It is available in stock in all grain sizes (Fepa F120 to F1500).
