White corundum 24# WA/white fused alumina F24 for sandblasting of aerospace parts
White corundum 24# WA/white fused alumina F24 for sandblasting of aerospace parts is a high-purity premium abrasive specifically designed for precision sandblasting treatment of aerospace structural parts, aviation aluminum alloys, titanium alloy components and aerospace precision castings. Manufactured from high-quality alumina raw materials through high-temperature electric melting, crystallization and strict FEPA standard grading, this abrasive features high hardness, sharp cutting performance and ultra-low impurity content, fully complying with the strict surface treatment standards of the aerospace manufacturing industry.
F24 white corundum boasts uniform particle size distribution and excellent particle toughness, with no oversize grains or fine powder impurities. Its moderate grain size balances high blasting efficiency and precise surface finishing, making it the ideal coarse abrasive for aerospace workpiece pretreatment. It can thoroughly remove surface oxide scales, welding slag, machining burrs and rust layers without causing excessive material loss or deep surface damage to high-precision aviation parts, effectively protecting the dimensional accuracy of aerospace components.
With ultra-low iron content and stable chemical inertness, WA24# white fused alumina leaves no ferrous residue after blasting, avoiding surface contamination and secondary oxidation of aerospace alloys. It can form a uniform and consistent matte roughness on workpiece surfaces, greatly improving the adhesion strength of subsequent thermal spraying, coating and anodizing processes, which is crucial for improving the wear resistance and corrosion resistance of aerospace parts.
Characterized by strong self-sharpening performance, low breakage rate and stable batch consistency, F24 white corundum features high blasting efficiency and long service life. It is widely recognized as a standard special abrasive for aerospace precision sandblasting, suitable for mass production and high-standard surface finishing of various aviation precision components.
