Abrasive Media Knowledge is hard to come by. Here, we break down exactly how different abrasive medias are constructed and what applications they are best suited for.
Mohs Hardness: 7-8 Bulk Density: 90-105 lbs cuft Made of Spherical, Angular, Sub-Angular and Oval Shaped Abrasives Significantly Delays Flash Rust Good replacement of Garnet - Cuts Faster (at all pressures tested) and Uses Less Abrasive to complete same job Beryllium and Free Silica Not Listed on SDS (not detected)
Mohs Hardness: 8-9 Bulk Density: 110 lbs cuft Hard and long lasting abrasives Typically used in blast cabinet and rooms because of recyclability Used in Vibratory Media as a cutting agent Aluminum oxide used as a grinding and polishing media Very hard and sharp abrasive
Mohs Hardness: 5.5-6.6 Bulk Density: 100 lbs cuft Made of 100% Recycled Glass Safe For Use Around Water American Made Contains less than 1% free silica Non-reactive & inert Beryllium is not listed on SDS CARB Approved / QPL Approved / Mil-Spec, SSPC AB-1, MIL-A-22262B(SH)
Mohs Hardness: 6.5-7 Bulk Density: 140 lbs cuft Used in Sandblast and Waterjet Relatively Hard Mined Mineral Heavy Abrasive Requires Higher Pressures to be effective Less than 10% Mined in the USA
Mohs Hardness: 7 Bulk Density: 160 lbs cuft Hard, Heavy good etching abrasive Breaks down in small angular pieces Wear on nozzles and hoses Angular Shaped / Dark Grey or Black color
Mohs Hardness: 3-4.5 Bulk Density: 55 lbs cuft 100% Recycled Material Good for coating removal without damaging the substrate Military used Plastic Abrasive to replace toxic chemical stripping Blast Cleaning, Deflashing and Deburring product Good abrasive to deburr machined aluminum parts Used in Mobile applications along with Blast Cabinets and Blast Rooms
