Why Choose Staurolite Sand 70 Mesh for Industrial Blasting
Staurolite is prized in the surface preparation industry for its sub-angular particle shape, moderate hardness, and exceptionally low free-silica content. The 70 mesh grade is particularly effective for applications demanding a fine, even profile—typically in the 1.5 to 2.5 mil range—without the surface contamination risks associated with slag or mineral slag abrasives.
Unlike garnet, which can fracture into sharp, embedding particles, staurolite tends to wear gradually, maintaining a consistent cutting action throughout its usable life. This makes it a preferred choice for blasting stainless steel fabrications, aluminum boat hulls, and precision-engineered components where surface integrity is non-negotiable.
Key Performance Characteristics
- Controlled profile: Produces a tight, repeatable anchor pattern ideal for thin-film coatings and high-build epoxies.
- Low iron content: Minimizes the risk of ferrous staining or corrosion on stainless steel and aluminum substrates.
- Low dusting: Generates less airborne particulate compared to coal slag or copper slag, improving operator visibility and safety.
- Recyclable: Suitable for multiple blast cycles in contained or reclaim systems, reducing media consumption and disposal costs.
Typical Applications
Staurolite Sand 70 mesh is specified across a range of industrial and marine surface preparation tasks:
- Stainless steel fabrication: Removal of heat tint, weld scale, and light rust without iron contamination.
- Aluminum surface prep: Profiling aluminum hulls, tanks, and structural components prior to coating.
- Non-ferrous casting cleaning: Deburring and surface finishing of brass, copper, and zinc castings.
- Thin-coat profile blasting: Achieving the fine anchor pattern required for zinc-rich primers, powder coatings, and thin-film epoxies.
- Maintenance blasting: Spot repair and touch-up work on bridges, storage tanks, and process equipment.

Applications
Common industrial uses for this abrasive.
Stainless Steel Blasting
Removes heat tint and weld scale without ferrous contamination. Ideal for food-grade, pharmaceutical, and architectural stainless fabrications.
Aluminum Surface Preparation
Profiles aluminum hulls, tanks, and structural components before painting or coating. Low embedment preserves surface integrity.
Thin-Coat Profile Blasting
Achieves the fine, uniform anchor pattern required for zinc-rich primers, powder coatings, and high-build epoxies.
Non-Ferrous Casting Cleaning
Deburrs and finishes brass, copper, and zinc castings without altering critical dimensions or introducing iron residue.
