The result is an extremely hard, blocky, angular material that combines fast cutting speed with exceptional recyclability \u2014 making it the benchmark abrasive for industrial surface preparation worldwide.<\/p>\n<p>With a Mohs hardness of 9 \u2014 just below diamond (10) and silicon carbide (9\u20139.5) \u2014 aluminum oxide is hard enough to aggressively profile carbon steel, stainless steel, aluminium alloys, titanium, and glass, yet it fractures in a controlled manner that continually exposes fresh cutting edges rather than rounding off. This self-sharpening behavior is one of the primary reasons aluminum oxide maintains consistent surface profile performance across 20\u201330 blasting cycles, far exceeding single-use slag media.<\/p>\n<p>Jiangsu Henglihong Technology Co., Ltd. produces and exports aluminum oxide abrasive in both brown (BFA) and white (WFA) grades, available in the full commercial grit range from 12 to 320, in 25 kg bags, 1,000 kg jumbo bags, and full container loads for international B2B buyers.<\/p>\n<div class=\"hlh-cl-highlight\"><p><strong>Key distinction:<\/strong> Aluminum oxide abrasive for blasting is a different product from aluminum oxide bonded to sandpaper or grinding wheels.

Both share the same Mohs hardness of 9, but differ in purity, cost, and optimal application range.<\/p>\n<p><strong>Brown Aluminum Oxide (BFA)<\/strong> is produced from bauxite and contains 95\u201397% Al\u2082O\u2083 with small amounts of TiO\u2082, SiO\u2082, and iron oxides, which give it its characteristic brown color and contribute to its slightly tougher fracture behavior. BFA is the workhorse of industrial blasting \u2014 aggressive, highly recyclable, and significantly lower in cost than WFA. It is the correct choice for structural steel preparation, coating adhesion profiling, and general surface cleaning where the substrate is not sensitive to trace iron contamination.<\/p>\n<p><strong>White Aluminum Oxide (WFA)<\/strong> is produced from Bayer-process alumina and achieves 99%+ purity. The absence of iron-bearing impurities makes it chemically inert and completely non-contaminating \u2014 critical for blasting stainless steel (where iron contamination causes rust staining), titanium alloys, aluminium before anodising, and semiconductor or medical device components. WFA is also the preferred media for glass engraving and fine decorative blasting where the brown color of BFA media could affect substrate appearance.<\/p>\n<div class=\"hlh-cl-infobox\"><p><strong>Rule of thumb:<\/strong> Use BFA for everything that is carbon steel or where contamination is not a concern.
