White Fused Alumina (WFA) for Resin Grinding Disc
Introduction
White Fused Alumina (WFA) is a high-purity abrasive material made from calcined alumina in electric arc furnaces at temperatures above 2000°C. Known for its exceptional hardness, sharp edges, and thermal stability, WFA is widely used in resin-bonded grinding wheels and cutting discs. Its superior performance makes it ideal for precision grinding, surface finishing, and metalworking applications.
Key Features of WFA for Resin Grinding Discs
1. High Hardness & Durability
WFA has a Mohs hardness of 9.0, second only to diamond and silicon carbide.
Provides excellent cutting efficiency and longer service life compared to brown fused alumina.
2. Sharp & Friable Grains
The crystalline structure of WFA breaks down under pressure, continuously exposing fresh cutting edges.
Ensures consistent grinding performance with minimal loading.
3. High Purity & Chemical Stability
Contains over 99% Al₂O₃, reducing impurities that can affect grinding quality.
Resistant to chemical reactions, making it suitable for stainless steel, titanium, and other alloys.
4. Thermal Resistance
Withstands high temperatures without losing cutting efficiency.
Prevents premature wear in high-speed grinding applications.
5. Uniform Grain Size Distribution
Precisely graded grains ensure smooth operation and reduce vibration.
Enhances surface finish and dimensional accuracy in precision grinding.
Applications of WFA in Resin Grinding Discs
WFA is widely used in resin-bonded abrasive tools for:
Metal Grinding & Finishing: Ideal for carbon steel, alloy steel, and hardened metals.
Stainless Steel & Titanium Processing: Minimizes heat-induced discoloration.
Tool & Cutter Sharpening: Provides a fine finish with minimal burrs.
Aerospace & Automotive Components: Ensures high precision in critical parts.
