If the metallographic fine polishing surface of earlier gray cast iron samples was always not ideal, and it was not a worry, and it took time and effort to grind again and again, thank you for this aluminum oxide polishing solution, which saved the metallographic polishing of my gray cast iron samples! So perhaps starting to use the American QMAXIS aluminum oxide polishing solution could be a small and gentle turning point.


I have never explored new ideas and have always followed the old path. Traditional and conservative, with the advancement of technology and the improvement of experimental requirements, I can no longer keep up with the pace. Although the preparation of gray cast iron samples is simple, with the improvement of technical requirements, the original process can no longer meet the requirements. Fortunately, I encountered the QMAXIS aluminum oxide polishing solution and used it to polish, resulting in an ideal effect on the surface of the sample that has never been achieved before. The high-definition images under the microscope provide the conclusion.

The aluminum oxide polishing solution I used was introduced by an old classmate, and the supplier is Kemai Testing (Nanjing) Co., Ltd. The product is imported from the United States with original packaging and the brand is QMAXIS. His aluminum oxide polishing solution has multiple models, universal, agglomerated, and non agglomerated, with a particle size ranging from 0.05 μ M to 1 μ M has both, following the advice of the pulse detection application engineer, I am using 1µ The non agglomerated alumina suspension is really useful. This is not true. When the sample is observed under a microscope, the graphite flakes are evenly distributed in the pearlite matrix and are clearly visible.

For making metallographic samples of gray cast iron, this aluminum oxide polishing solution is used for fine polishing, and the effect is visible μ m. 0.3 μ M and 0.05 μ M all have, each style exudes the rigor and focus of QMAXIS, high-quality aluminum oxide polishing fluid, and accompanied by professional and dedicated application engineers to answer questions and solve doubts. Thank you for this aluminum oxide polishing solution, which saved the metallographic polishing of my gray cast iron samples. Thank you to Kemai Testing for providing such good service, which has given my uneasy heart support.
