Alumina polishing solution is used by metallographic colleagues every day, and most material sample preparation, such as iron based metals, copper, polymers, minerals, microelectronics, precious metals, etc., will use alumina polishing solution for fine polishing. Undoubtedly, the subsequent fine polishing is at the nanoscale, and the commonly used alumina polishing fluid has an abrasive particle size of 0.05 μ m. Meet the requirements for high-quality sample preparation. There are many alumina polishing solutions in the market, what is high-quality alumina like?

    Chaineng Metallographic Editor recommends a high-quality aluminum oxide polishing solution imported from the United States to our friends!


Aluminum oxide polishing solution is used for the ultimate polishing of samples, with the aim of removing surface deformation layers that cannot be seen by the naked eye. It is used to evaluate samples using high-power objective lenses, polarized light, differential interference contrast, or to provide a deformable sample surface when using EBSD technology. Therefore, the quality requirements for alumina polishing fluid are very high. The aluminum oxide polishing fluid used for pure mechanical polishing does not allow agglomeration, and must have good dispersibility in order to efficiently remove materials and achieve excellent surface treatment results. However, the common aluminum oxide polishing solution on the market always fails to solve the problem of agglomeration, which brings difficulty to the sample preparation work.

    This imported aluminum oxide polishing solution from the United States does not agglomerate and has excellent dispersibility, with a particle size of 0.05 μ m. The abrasive particles are uniform and the removal rate is excellent! 8.5 pH, weakly alkaline, mainly used for pure mechanical polishing methods to remove material deformation layers and scratches. More suitable for the ultimate polishing of metallographic samples such as cast iron, steel, stainless steel, copper, polymers, minerals, microelectronics, and precious metals. It can effectively remove scratches and perfectly reproduce the microstructure morphology.

    This alumina polishing fluid is widely used, and according to statistics, it is being used in key laboratories in multiple countries around the world. Whether it is research, teaching, quality control, testing, or other high-quality metallographic sample preparation, it can meet the requirements. Good quality has been proven through practice. A high-quality alumina polishing solution should be like this!
