The Brown Fused Alumina segmentation by application reflects four primary end‑uses that together drive the market’s revenue. Sandblasting accounts for the largest share, roughly 35 % of total sales, because it remains the dominant abrasive for surface preparation in automotive, aerospace, and construction sectors; its high impact resistance and angular particle geometry enable efficient material removal at scale. Polishing follows with an estimated 30 % contribution, serving semiconductor wafer cleaning, metal finishing, and glass polishing where fine surface finish and low contamination are critical. Cutting represents about 20 % of the market, primarily in stone, tile, and hard‑metal machining where the high hardness of brown fused alumina delivers consistent kerf quality and reduced tool wear. Finally, Grinding holds a 15 % share, utilized in precision grinding of ceramics and engineered components; its ability to maintain dimensional stability under high thermal loads sustains demand. Collectively, these application segments delineate demand drivers and allocate revenue across the Brown Fused Alumina market.
