Black Aluminum Oxide 220 mesh

Understanding Black Aluminum Oxide 220 Mesh

Black aluminum oxide is a tough, synthetic abrasive produced by fusing calcined bauxite in an electric arc furnace. The 220 mesh grade represents a fine particle size distribution, typically used where a smooth surface profile and consistent finish are required. Its high density and angular structure allow it to fracture slowly under impact, continuously exposing fresh cutting edges. This self-sharpening characteristic makes it economical for recycling in blast cabinets and recovery systems.

Industrial Applications and Surface Finish

This 220 mesh abrasive is commonly specified for:

• Precision cleaning: Removing light rust, mill scale, and surface oxides from ferrous and non-ferrous metals.
• Surface preparation: Creating a uniform anchor profile for coatings, paints, and thermal spray applications.
• Deburring and finishing: Smoothing machined components, removing fine burrs, and achieving a matte finish.
• Etching and texturing: Preparing surfaces for bonding, plating, or non-slip coatings.

The fine particle size helps operators achieve a lower surface roughness (Ra) compared to coarser grits, making it suitable for components where dimensional tolerance is critical.

Selection and Handling Tips

When selecting Black Aluminum Oxide 220 mesh, consider your blasting equipment type (suction or pressure), nozzle size, and desired surface profile. This fine mesh performs best in dry blasting systems with adequate dust collection. For wet blasting applications, confirm compatibility with your slurry system. Always store the abrasive in a dry, covered area to prevent moisture absorption, which can cause clumping and inconsistent flow through metering valves.
