Particle Size and Shape of Abrasives

The behavior of an abrasive material is influenced by the hardness, size, and shape of the particles. A harder particle will be more aggressive in altering the surface of the work piece. Larger particles generate higher impact force removing the material surface quicker and producing a heavier texture. Particle shape also plays a role. Get price

Thanks for the chart Ron. First because it correlates Scotch Brite pads to grit size, and secondly because I just realized that 3M Wetordry in fresh 400 grit is equal to P700. I've always wet sanded car/motorcycle painted parts with well used 400 paper and was happy with the results. Get price

Grit and Powder Sizing

Abrasive powders commonly refer to any size finer than #240 grit, and are called microgrits. Each mesh size has an equivalent micron size designation, i.e. 37, 29, 17, 13, 9, 5, 7, 3. As the micron size number gets lower, the size of the material is finer. Grit and Powder Sizing - Table of Grit Sizes GRIT SIZING FOR ALUMINUM OXIDES AND SILICON Get price

What is the Grit Standard?

Oct 30, 2017In FEPA (European standards) there are separate grit size standards for coated abrasives like sandpaper (FEPA P) and bonded abrasives like most stones and grinding wheels (FEPA F). Grit designations under different systems have different ranges of particle size considered as acceptable maximum, minimum, and average effective size, all in microns. Get price

Introdution of Grit/Grain Sizes for Diamond and CBN

So the coarse grain size is suitable for rough grinding and the fine grit size is proper for finish grinding. The grain size is usually indicated according to the FEPA standard. Grit size is measured in terms of the rated mesh size of several screens and denotes the approximate particle diameter. Get price

Green Silicon Carbide Specifications

Black SiC will contain some free silicon and carbon and thus is not as pure as green SiC. Black will range in purity from 97-99% pure, depending on grit size. Green SiC is made from Silica sand and coke, and is extremely pure. Hexagonally shaped, it breaks into very sharp particles. Our green SiC is 99.5% pure, exceeding JIS, ISO, FEPA standards.
