A procurement engineer ordering aluminum oxide &#8220;80 grit&#8221; without specifying the applicable standard may receive a product with a mean particle diameter 20\u201330% different from what the process specification requires. For industrial blasting, lapping, sandcarving, and lapidary applications where the grit size directly determines the surface profile or finish quality achieved, this discrepancy is not a minor inconvenience \u2014 it is a root cause of surface preparation failures, profile non-conformances, and rejected blasting inspection results.<\/p>\n\n<p>This complete reference guide explains the major grit sizing standards in use globally, provides cross-reference tables between standards, and includes media-specific size charts for each principal abrasive family.

The F-series (loose grain for blasting and lapping) and P-series (coated abrasive products) use the same number system but define different particle size windows. FEPA F 80 \u2260 FEPA P 80.<\/li>\n  <li><strong>ANSI B74.12<\/strong> \u2014 the US standard for bonded and coated abrasive grain, maintained by the American National Standards Institute. Numbers broadly correspond to FEPA at coarser sizes but diverge significantly at finer grits.<\/li>\n  <li><strong>JIS R6001<\/strong> \u2014 the Japanese Industrial Standard for abrasive grain sizing. Used for alumina and SiC products manufactured or specified in Japan, Taiwan, and South Korea. Follows FEPA closely at most sizes but with slightly different sieve window definitions.<\/li>\n  <li><strong>US Mesh (Tyler and US Standard)<\/strong> \u2014 wire sieve mesh number = number of wires per inch. Used for natural minerals (garnet, copper slag) and for coarser grain sizes where FEPA numbers are not applied. Higher mesh number = smaller particle. Not the same as grit number.<\/li>\n<\/ul>\n\n<div class=\"hlh-notice\">\n  <p><strong>Always specify the standard when ordering:<\/strong> When issuing a purchase order for abrasive media, always state the applicable standard \u2014 &#8220;80 grit FEPA F&#8221;, &#8220;80 mesh US Standard&#8221;, or &#8220;SAE J827 S-230&#8221;.

<p>These are working approximations. Actual profile achieved varies with blast pressure, nozzle wear, substrate hardness, and media breakdown state. Always measure achieved profile on a test panel under your specific equipment conditions before committing to a production blast specification.<\/p>\n<\/div>\n\n<h2 id=\"grit-faq\">Frequently Asked Questions<\/h2>\n<div class=\"hlh-flist\">\n\n  <div class=\"hlh-fitem\">\n    <div class=\"hlh-fq\">Why does the same FEPA grit number cut differently on different materials?<\/div>\n    <p class=\"hlh-fa\">The FEPA grit number defines the particle size \u2014 the physical dimensions of the abrasive grain \u2014 not the cutting energy or profile depth it will produce. The actual cutting outcome depends on both particle size and the hardness differential between the abrasive and the substrate. The same F 80 aluminum oxide grain that produces Rz 25\u201340 \u00b5m on mild carbon steel (200 HV) will produce a shallower profile on hardened tool steel (600+ HV) and a deeper profile on soft aluminum alloy (60\u201380 HV), because the substrate&#8217;s resistance to plastic deformation is what determines how deeply each particle penetrates on impact. Always specify and verify profiles on the actual substrate material under the production blast conditions.<\/p>\n  <\/div>\n\n  <div class=\"hlh-fitem\">\n    <div class=\"hlh-fq\">Is FEPA F 80 the same as FEPA P 80?<\/div>\n    <p class=\"hlh-fa\">No. FEPA uses two parallel numbering series for the same grit number range. The F-series (Federation grain) defines particle size distribution for loose abrasive grain used in blasting, lapping, and bonded abrasives manufacturing. The P-series (Precision grain) defines particle size distribution for grain used in coated abrasive products (sandpaper, abrasive belts). At the same number \u2014 for example, F 80 vs P 80 \u2014 the P-series grain is actually finer than the F-series grain. P 80 has a maximum particle size approximately equivalent to F 100. Never use F-series specifications to order P-series product or vice versa.<\/p>\n  <\/div>\n\n<\/div>\n\n<div class=\"hlh-cta\">\n  <h2>Abrasive Media in Any Grit Size from Henglihong<\/h2>\n  <p>Al\u2082O\u2083 and SiC in F 12 through F 320, garnet in #12 through #120 mesh, steel shot and grit in the full SAE range.
