White Fused Alumina Abrasives

1. Application Overview

White fused alumina (WFA) is a primary raw material in the production of bonded and coated abrasives. Its sharp angular grains, high hardness, and excellent purity provide superior cutting efficiency, long service life, and consistent performance across a variety of abrasive products.

2. Application Scenarios

• • Sandpaper manufacturing: Ensures strong bonding, sharp cutting, and long-lasting sheets for wood, metal, and painted surfaces.
• • Grinding wheel production: Provides consistent grit shape and hardness for efficient material removal in metal and stone grinding.
• • Oil stone and honing stones: Delivers sharp cutting edges and controlled abrasion for tool sharpening and surface finishing.
• • Coated abrasives for industrial use: Used in belts, discs, and specialty coatings for precision finishing applications.

3. Recommended Grit Size

Selecting the correct grit size depends on the type of abrasive product and the desired cutting performance:

Practical Tips

• Bonding material: Choose appropriate resins or adhesives to maximize grit retention and wheel life.
• Grit distribution: Ensure uniform spread to prevent uneven cutting and surface defects.
• Pressing & curing: Maintain correct pressure and temperature during production for consistent hardness.
• Quality inspection: Check for grit size, bonding strength, and cutting performance before shipment.
