In the metallographic laboratory, there are piles of various types of metallographic sandpaper, including thick, fine, and neither coarse nor fine. However, one of the favorite ones is the QMAXIS metallographic sandpaper imported from the United States, which always performs outstandingly during sample preparation. It never drops particles randomly or deforms due to prolonged grinding and soaking in water, resulting in excellent performance!

This QMAXIS metallographic sandpaper, imported from the United States with original packaging from Kemai Testing, is currently not common on the market. It is only sold by Kemai Testing Nanjing Company and its authorized agents. The quality is indeed extraordinary, and the abrasive is not easy to fall off. This is too important!


After comparison, we found that the distribution of silicon carbide abrasive particles in QMAXIS metallographic sandpaper is very uniform and dense, and can be felt very delicate by hand, accompanied by obvious frictional resistance and tactile sensation. Using P180, P320, and P600 for rough grinding, the same sample and loading force, the grinding time is faster than ordinary sandpaper. For example, for printed circuit board samples, using P320 or P600 labels, the average grinding time is one and a half minutes, It indicates that its grinding performance is very good. What is particularly pleasing is that after grinding each grade, it can smoothly enter the next process without worrying about falling off or the abrasive causing secondary scratches on the sample. It can be seen that the manufacturing process of this metallographic sandpaper is very good.

Another favorite feature of this metallographic sandpaper is that even under long-term sample preparation working conditions, it does not deform due to prolonged soaking time, nor does it experience tearing or wrinkling due to sample loading friction. It has always been tightly attached to the grinding disc, with smooth and consistent performance, making the sample preparation work very satisfactory in terms of quality and efficiency, The quality of this metallographic sandpaper is quite good.


This imported QMAXIS metallographic sandpaper from the United States has won the love of all metallographic engineers in our laboratory for its excellent quality and satisfactory performance, and everyone will prioritize using it to prepare samples. The rare QMAXIS metallographic sandpaper on the market, the abrasive is not easy to fall off and does not deform when exposed to water. We all use it! If you also want to use it, you can directly contact Kemai Testing Company, Baidu Yisou" Pulse detection” You can find it.
