COPPER SLAG
Premium Copper Slag
A dense, angular, and hard synthetic mineral by-product. Highly regarded as a safe, eco-friendly, and highly efficient abrasive medium for surface preparation, as well as a robust concrete aggregate.
Copper Slag Overview
Copper slag is a tough, synthetic by-product generated during the smelting and refining of copper ore. Upon being rapidly cooled (quenched) in water, it fractures into hard, glassy, angular granules composed primarily of Iron Silicate.
Due to its exceptionally high specific gravity and sharp, angular structure, it possesses incredible kinetic energy upon impact. This makes it a vastly superior and faster-cutting alternative to traditional sandblasting. Crucially, it contains virtually zero free crystalline silica, entirely eliminating the risk of silicosis for operators.
In addition to surface preparation, its density, chemical stability, and low water absorption make it a highly desirable fine aggregate for heavy-weight concrete, roofing granules, and specialized civil engineering applications.
- Delivers aggressive, fast surface profiling (SA 2.5 / SA 3.0)
- Extremely low free silica makes it an OSHA-compliant abrasive
- High specific gravity minimizes dusting during blast operations
- Consumes less material per square meter compared to garnet or sand
- Excellent high-density fine aggregate for heavy-weight concrete
- Chemically stable, non-leaching, and environmentally sound

Industrial Applications
Shipyard Surface Prep
The standard abrasive for removing heavy rust, mill scale, and marine coatings from ship hulls and steel structures quickly and efficiently.
Pipe & Tank Blasting
Provides the optimal angular surface profile required to ensure excellent adhesion for high-performance industrial epoxy and urethane coatings.
Heavy-Weight Concrete
Used as a dense fine aggregate replacement to produce high-density concrete required for structural weighting and radiation shielding.
Roofing Granules
Its black, glassy appearance and UV resistance make it an ideal granule for manufacturing durable asphalt roofing shingles.
