The coarseness of the paper is indied by a nuer: the nuer of grains of silicon carbide per square inch. So, for example, 180 grit paper is coarser than 1200. The grinding procedure involves several stages, using a finer paper (higher nuer) for each successive stage.

Metallographic Abrasive Grinding
Soft non-ferrous metals - Initial grinding is recommended with 320 grit SiC abrasive paper followed by 400, 600, 800 and 1200 grit SiC paper. Because these materials are relatively soft they do not easily break down the SiC paper. Thus initial grinding with 320 grit is
