Metallographic Sandpaper: Correct Selection for Perfect Results
During the preparation of metallographic samples, whether they are metals, composite materials, or electronic materials, the use of metallographic sandpaper is usually the first step. The purpose is to remove the damage and deformation layer caused by the cutting process, which is the coarse grinding stage and serves as preparation for subsequent polishing. This step is critical because if not handled properly, it will affect the results of later processes and may even prevent the sample from being properly ground, making it impossible to perform the final metallographic analysis. With this in mind, the editors at Lianneng Metallography have a few suggestions to share, which should help improve your sample preparation work.
