Import Brown Fused Alumina Grit (F24) — Buy in Bulk from Supplier in China

Brown fused alumina grit F24 is a coarse-grade abrasive produced by electric arc fusion of high-purity bauxite, yielding a tough, angular grain with a typical hardness of 9 on the Mohs scale. The F24 designation corresponds to a particle size range of 710 to 500 microns, as defined by the FEPA standard, ensuring consistent performance in heavy-duty blasting and grinding operations. This grade is chosen for applications requiring aggressive material removal without excessive dust generation.

The material’s chemical composition is predominantly aluminium oxide (Al2O3) with a standard minimum content of 95%, complemented by minor oxides such as titanium and silicon that contribute to its brown colour and fracture resistance. Typical bulk density for F24 grit is 1.8 to 2.0 g/cm³, with a refractoriness exceeding 1800°C, making it suitable for use in high-temperature environments such as foundries and steel mills. The angular shape of the grains provides sharp edges for efficient cutting action, while the fused structure resists fragmentation under mechanical stress.

F24 grit is primarily used in surface preparation for coatings, cleaning castings and forgings, and as a media in shot blasting cabinets. Industrial buyers in shipbuilding, petroleum, and metal fabrication sectors rely on this grade for its ability to remove rust, scale, and old paint from steel substrates. Sourcing terms often include bulk packaging in 25 kg or 1-tonne jumbo bags, with FOB or CIF incoterms negotiated based on order volume.
