-->\n  <h2 id=\"hardness\">Hardness Comparison \u2014 Mohs Scale<\/h2>\n\n  <p>Hardness is the single most important factor in determining how aggressively a media cuts into a surface and how long individual particles remain effective. The <strong>Mohs hardness scale<\/strong> runs from 1 (talc) to 10 (diamond). The chart below maps each media type across that scale \u2014 a longer bar means a harder, more aggressive abrasive.<\/p>\n\n  <p>An important distinction: steel abrasives are rated on the <strong>Rockwell C (HRC) scale<\/strong> rather than Mohs, because they are metallic rather than mineral.

class=\"faq-body\">\n        <p>Silicon carbide is the hardest at Mohs 9\u20139.5, followed by aluminum oxide at Mohs 9. For most industrial surface preparation work, aluminum oxide provides the best combination of hardness, recyclability, and cost-effectiveness and is the more practical choice. Silicon carbide is reserved for niche applications like ceramics, carbide tooling, and glass engraving where aluminum oxide cannot achieve the required result.<\/p>\n      <\/div>\n    <\/details>\n    <details>\n      <summary>Which abrasive media creates the deepest surface profile?<\/summary>\n      <div class=\"faq-body\">\n        <p>Steel grit (high-hardness grade, HRC 60\u201366) creates the deepest anchor profile, typically reaching 2.5\u20135.0 mil in wheel-blast operations. Coarse aluminum oxide in a pressure blast system follows closely at 1.5\u20134.0 mil depending on grit size and operating pressure. For applications requiring profiles above 3.0 mil, steel grit in a wheel-blast system is the standard industrial solution.<\/p>\n      <\/div>\n    <\/details>\n    <details>\n      <summary>What is the most cost-effective abrasive media overall?<\/summary>\n      <div class=\"faq-body\">\n        <p>Cost-effectiveness must be evaluated on a per-cycle basis, not a per-pound basis. Steel grit and steel shot, despite their high upfront cost, typically deliver the lowest per-cycle media cost at production scale due to their 100+ cycle recyclability in wheel-blast equipment. For lower-volume pressure blast and cabinet operations, aluminum oxide (5\u201310 cycles) offers the best balance. Single-use media like garnet and crushed glass are the cheapest per bag, but the highest cost per ton of steel processed.<\/p>\n      <\/div>\n    <\/details>\n    <details>\n      <summary>What is the difference between grit and mesh numbering?<\/summary>\n      <div class=\"faq-body\">\n        <p>For mineral and synthetic abrasives (aluminum oxide, garnet, silicon carbide, glass beads), higher grit\/mesh numbers mean finer, smaller particles: 36 grit is coarse, 220 grit is fine. For steel grit (SAE G-series), the opposite applies \u2014 G10 is large\/coarse, G120 is small\/fine. For steel shot (SAE S-series), larger numbers mean larger particles: S110 is small, S780 is large. Always verify which numbering convention a product datasheet uses before specifying a size.<\/p>\n      <\/div>\n    <\/details>\n    <details>\n      <summary>Can I mix different abrasive media types?<\/summary>\n      <div class=\"faq-body\">\n        <p>Generally, no \u2014 blending different media types is not recommended. Mixed media produces unpredictable surface profiles and contamination that can interfere with coating adhesion. Different media also have different optimal operating parameters (pressure, nozzle type, reclaim settings). The only exception is deliberate production blending of different sizes of the same media type to achieve a specific profile range \u2014 a practice used in some aerospace finishing applications with glass beads or aluminum oxide. Always consult the media manufacturer before attempting any blend.<\/p>\n      <\/div>\n    <\/details>\n  <\/div>\n\n\n<\/article>","protected":false},"excerpt":{"rendered":"<p>Abrasive Media Comparison Chart: Hardness, Grit &amp; Cost Guide Every  [&#8230;]<\/p>","protected":false},"author":1,"featured_media":12461,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[62,175,138],"tags":[],"class_list":["post-12422","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","category-industry","category-resource"],"_links":{"self":[{"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/posts\/12422","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/comments?post=12422"}],"version-history":[{"count":5,"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/posts\/12422\/revisions"}],"predecessor-version":[{"id":12495,"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/posts\/12422\/revisions\/12495"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/media\/12461"}],"wp:attachment":[{"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/media?parent=12422"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/categories?post=12422"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hlh-js.com\/fr\/wp-json\/wp\/v2\/tags?post=12422"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
