Metallographic Specimen Preparation Basics

Abrasive Selection - The most common abrasive used for planar grinding metal and polymer metallographic specimens is silicon carbide (SiC). Silicon carbide is an excellent abrasive for planar grinding because it is very hard and maintains a sharp cutting edge as it breaks down during cutting. SiC abrasives are typically listed by the grit size.
