Black Fused Alumina

Description：

Black fused alumina (also known as black aluminum oxide) is a high-performance abrasive material widely used for metal surface cleaning, rust removal, and heavy-duty industrial sandblasting. It is produced by smelting bauxite and iron oxide at high temperatures, resulting in a dense, multi-angular grain structure. With its excellent impact resistance, cost-effectiveness, and superior surface profiling capabilities, it is ideal for large-scale surface preparation projects requiring consistent surface roughness.

Key Features:

• Moderate Hardness: Reduces heat generation during grinding while maintaining effective cutting ability.

• Excellent Toughness: Performs well in heavy-duty abrasive applications with minimal particle breakdown.

• Strong Impact Resistance: Suitable for aggressive blasting and rough surface cleaning.

• Cost-Effective: Offers high performance at competitive pricing, making it ideal for industrial-scale use.

• Optimized Surface Finish: Delivers consistent surface roughness, improving coating adhesion.

We offer a wide range of particle sizes to meet various sandblasting and polishing needs.
