Garnet sand 30-60 for sandblasting of aerospace parts
30-60 mesh garnet sand is a premium eco-friendly abrasive specially engineered for precision sandblasting and surface preparation of aerospace components. Refined from high-purity natural garnet ore through multiple washing, drying, crushing and precise mesh grading processes, this abrasive features uniform particle distribution, sub-angular grain structure and ultra-low impurity content, fully meeting the strict surface treatment standards of the aerospace industry.
With a Mohs hardness of 7.5–8.0 and excellent particle toughness, this 30/60 mesh garnet delivers moderate and stable cutting force without damaging high-precision aerospace substrates such as aluminum alloy, titanium alloy and composite materials. It efficiently removes surface oxide layers, welding spatter, residual coatings and tiny burrs, creating a consistent, smooth and standardized surface profile that greatly enhances the adhesion of subsequent spraying, anodizing and thermal coating processes.
Free of free silica and toxic substances, the garnet sand eliminates silicosis risks and heavy metal pollution, complying with international aerospace safety and environmental regulations. Compared with traditional abrasives, it generates minimal dust, reduces equipment wear, and offers outstanding recyclability, effectively lowering overall operating costs for aerospace manufacturing and maintenance projects. It can stably achieve SA2.5 to SA3 high-standard blasting finishes required for aviation parts.
Tailored for high-precision industrial scenarios, 30-60 mesh garnet sand balances cleaning efficiency and surface fineness perfectly. It is widely applied in surface treatment of aircraft structural parts, aviation engine accessories, aerospace precision molds and spacecraft components. As a reliable, cost-effective and quality-stable blasting media, it has become the preferred abrasive for professional aerospace surface finishing worldwide.
