Brown fused alumina 24# for sandblasting of aerospace parts
Brown Fused Alumina 24# is a high-performance industrial abrasive specially optimized for surface sandblasting treatment of aerospace structural components, aviation alloy parts, precision forgings and aerospace mechanical accessories. Produced from high-quality bauxite via high-temperature smelting, crushing and strict FEPA standardized grading, this abrasive features high hardness, excellent mechanical toughness and strong cutting force, meeting the rigorous quality and surface finishing requirements of the aerospace manufacturing industry.
24# brown fused alumina has uniform particle size distribution with few fine powders and zero oversized particles. Its reasonable grain structure achieves a perfect balance of efficient derusting, descaling and precise surface finishing. It can effectively remove surface oxide layers, welding residues, machining burrs and fatigue layers on aerospace parts without excessive material removal or surface damage, well protecting the structural integrity and dimensional accuracy of high-precision aviation workpieces.
With stable chemical inertness and low impurity content, this 24# brown alumina avoids surface contamination and residual pollution during blasting. It creates a uniform, fine matte surface and consistent roughness for aerospace parts, significantly enhancing the bonding performance of subsequent thermal spraying, anti-corrosion coating and surface modification processes, which greatly improves the wear resistance and service stability of aviation components.
Featuring outstanding self-sharpening property, low breakage rate and stable batch consistency, 24# brown fused alumina delivers high blasting efficiency and long service life. It is cost-effective and reliable for large-scale surface pretreatment and finishing of various aerospace parts, serving as a mainstream and trusted blasting abrasive for the aviation industry.
