Virgin Aluminum Oxide 36 mesh

Aggressive Surface Preparation with Virgin Alox 36 Grit

When a job demands a deep, angular anchor profile for heavy-duty coatings, thermal spray, or rubber lining, finer or less aggressive media will not suffice. Virgin Aluminum Oxide 36 mesh is specifically selected for its high cutting speed and ability to remove heavy mill scale, thick rust, and old coatings in a single pass. Its high purity and hardness minimize iron contamination on stainless steel and non-ferrous substrates, a critical requirement for sensitive applications.

This abrasive is a workhorse in fabrication yards, foundries, and heavy engineering shops. Its friable nature means the grains fracture under impact, continuously exposing new, sharp cutting edges. This self-sharpening characteristic ensures consistent performance throughout the media's usable life, delivering a uniform surface profile that coating inspectors and engineers can rely on.

Key Features and Performance Benefits

• First-pass, high-cut oxide grit: Formulated for maximum stock removal and rapid cleaning on hard metals.
• Consistent 36 mesh sizing: Tight particle distribution ensures a predictable, deep anchor profile for coating adhesion.
• Virgin, high-purity material: Minimizes the risk of ferrous contamination on stainless steel, aluminum, and other non-ferrous substrates.
• Self-sharpening friability: Grains fracture to reveal fresh cutting edges, maintaining speed and reducing media consumption compared to less friable alternatives.
• Versatile pack options: Supplied in 25 kg bags, 50 kg bags, 1-ton jumbo bags, bulk totes, and drums to match your site logistics and consumption rate.

Industrial Applications

Virgin Aluminum Oxide 36 mesh is specified across industries where surface integrity and coating performance are non-negotiable. Common applications include:

• Structural steel fabrication: Preparing beams, columns, and plate steel for industrial protective coatings and intumescent fireproofing.
• Foundry and casting cleaning: Removing sand, scale, and burrs from iron and steel castings without excessive metal removal.
• Thermal spray preparation: Creating the sharp, angular anchor profile required for the mechanical bond of arc spray, flame spray, and HVOF coatings.
• Shipyard and marine maintenance: Blasting hull plates, decks, and tanks to SA 2.5 (Near White Metal) standards before marine paint application.
• Rubber lining and composite bonding: Profiling metal surfaces to ensure a high-strength bond with rubber linings, FRP, and other composite materials.

Selection and Handling Guidance

For optimal results, maintain blasting pressure between 90-110 PSI and use a nozzle with a minimum 3/8-inch orifice for this coarse grit. Ensure your air supply is dry and oil-free to prevent contamination of the virgin abrasive. This media is suitable for both suction and pressure blast systems, as well as standard centrifugal wheel machines. Always store bags in a dry, covered area; moisture will cause clumping and disrupt metering in blast pots. While virgin aluminum oxide is highly recyclable, the 36 mesh size will fracture and generate fines with each cycle. Monitor your working mix and add fresh media regularly to maintain the specified profile depth.
