Brown Fused Alumina for Casting Sandblasting: The Preferred Abrasive for Efficient Surface Treatment

Brown Fused Alumina for Casting Sandblasting: The Preferred Abrasive for Efficient Surface Treatment

In the foundry, metalworking, and surface treatment industries, brown fused alumina is the core material for sandblasting, polishing, and cleaning processes due to its exceptional hardness and durability. As a professional abrasive supplier, we provide high-purity, precisely graded brown fused alumina to help customers improve processing efficiency and reduce overall costs.

Key Advantages of Brown Fused Alumina for Casting Sandblasting

1. Superior Cutting Performance

• With a Mohs hardness of 9.0 (Al₂O₃ ≥ 95%), it rapidly removes scale, burrs, and residual molding sand from castings, achieving 50%+ higher efficiency than silica sand.

2. Low Wear & Long Service Life

• High-toughness grains resist fracturing during blasting, enabling reuse and significantly reducing material waste.

3. Eco-Friendly & Safe

• Free from free silica dust, compliant with OSHA and EPA standards, eliminating worker silicosis risks.

Typical Applications

• Casting Cleaning: Removes flashes, adhered sand, and defects from steel/iron/aluminum castings.

• Surface Preparation: Creates uniform roughness for painting/plating substrates.

• Mold Maintenance: Efficiently cleans residual metal from mold surfaces.
