Structure is basically the spacing between abrasive grains.  An open structure would be 12 or higher while a closer structure would be 6 or so.  Here again, the structure depends on a variety of factors not the least of which is how difficult the material is to grind.

If you are roughing, choose a 36 to 80 grit. If you are intermediate grinding, use 80 through 180 grit. If you are finishing, use 220 through 240 grit.

According to the FEPA, the bulk density of an abrasive is the quotient of the mass and the volume a grain type poured out in a particular manner will occupy. The bulk density, also called bulk weight, is stated in g/cm3. The rounder the particles, the higher the packing density,

Corundum is the most frequently used abrasive. The purer the corundum, the harder it also is, which can be determined from the colour. The toughness can be increased by adding various metal oxides and by shortening the cooling process in production. The following distinctions are made: Brown fused alumina with

Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit).  Superfine grits run from 150 and higher.  Grinding wheels usually will be between 24 and 100 grit.  Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher.
