Precise Polishing with ALUMINA in Metallography
The significance of alumina as a polishing agent in metallography is based on a variety of factors. Alumina enables extremely precise sample preparation. Through different grain sizes, metallographers can tailor the polishing agent precisely to the specific requirements of the sample. Coarser polishing, fine grinding, or the final high-gloss polish—alumina offers the required versatility. Efficiency and reproducibility are additional strengths of alumina. With the targeted selection of grain size and accurate dosage of the polishing agent, highly precise results can be achieved. Particularly concerning microscopic examinations, alumina showcases its strengths. Here, minimal irregularities and flawless surfaces are crucial. Alumina enables a final polish that meets these requirements by producing surfaces of the highest precision and detail accuracy. Overall, the significance of alumina as a polishing agent in metallography is high. Its ability for precision, adaptation to different requirements, and the achievement of reproducible results make it an essential tool. The choice of the right grain size and adherence to specific working conditions are crucial to fully leverage the benefits of this polishing agent. It contributes to quality assurance and the attainment of reliable results in metallography. SCAN-DIA ALUMINA, based on aluminum oxide (Al2O3), is offered in three different grain sizes, each suitable for specific applications: 1 µ grain size: This grain size is excellent for coarser polishing work and removing material impurities. It is the ideal choice for preparing sample surfaces for further processing. 0.3 µ grain size: The medium grain size provides the perfect balance between abrasive performance and surface quality. It is ideal for the fine grinding and polishing phase, where precision and detail accuracy are crucial. 0.05 µ grain size: This finest grain size is suitable for the final polish of sample surfaces. It creates a flawless surface that meets even the highest standards, providing optimal conditions for microscopic examinations. The alumina is suspended in water to achieve the desired grain size. A precise mixture and suspension are necessary to obtain consistent results. In summary, alumina is a versatile polishing agent in metallography that meets the requirements of precision sample preparation at the highest level.
