White Corundum for Resin Grinding Discs – Premium Abrasive for Precision Grinding
Product Overview
White Corundum (Al₂O₃), also known as white fused alumina, is a high-purity, synthetic abrasive material widely used in resin-bonded grinding discs. With exceptional hardness (Mohs 9.0) and thermal stability, it delivers superior cutting performance for metal, alloy, and composite materials.
Our white corundum is specially processed for resin grinding applications, offering consistent grain shape, high self-sharpening ability, and minimal impurities—ensuring longer disc life and smoother finishes.
Key Features & Benefits
✅ High Purity (≥99.5% Al₂O₃) – Reduces contamination during grinding.
✅ Controlled Grain Size (F16-F1200) – Optimized for coarse to fine grinding.
✅ Low Iron Content (<0.05%) – Prevents discoloration on stainless steel & titanium.
✅ Excellent Fracture Toughness – Maintains sharp edges for consistent material removal.
✅ Thermal Resistance (Up to 1900°C) – Withstands high-speed grinding without degradation.
Recommended Applications
🔹 Metalworking – Stainless steel, aluminum, and titanium deburring/polishing.
🔹 Automotive – Brake pad shaping, engine component finishing.
🔹 Aerospace – Turbine blade edge grinding.
🔹 Tool Sharpening – Carbide tool refurbishment.
