Alodur® GF Brown Fused Alumina Grits
Peneq supplies Alodur® GF Brown Fused Alumina Grits, a high-performance abrasive material produced by fusing high-purity alumina in an electric arc furnace under tightly controlled conditions. The material is then crushed, ground, and precision-sized to ensure consistent performance.
To maintain product purity, residual magnetic iron generated during processing is removed using rare earth magnetic separation, resulting in low iron content in the final product.
Key Features & Benefits
- Manufactured from fused alumina in controlled electric arc furnace conditions
- Crushed, ground, and precision classified for consistent grit sizing
- Low iron content due to magnetic separation process
- High hardness and durability for abrasive applications
- Available in ANSI Table 2 and Table 3 standard sizings
- Suitable for a wide range of industrial grinding and finishing applications
