Brown Fused Alumina for Cutting Tools
Abrasive grain engineered for high-speed cutting discs, saw blades, and segment tools across multiple industries.
Why Use BFA in Cutting Tools?
Brown fused alumina (BFA) is widely used in the manufacture of cutting tools due to its high hardness, thermal resistance, and toughness. It supports fast material removal with minimal heat damage, making it ideal for bonded cutting wheels, reinforced cutoff discs, and composite blades.
- Sharp cutting edges with stable grain structure
- High thermal resistance prevents burning or warping
- Consistent performance in high-speed rotary tools
Cutting Tool Applications
- Resin-bonded cutoff wheels for steel and stainless steel
- Segmented blades for stone and construction cutting
- Chop saw and portable cutting discs
- Cutting tools for aluminum, rebar, cast iron, and alloys
BFA is often blended with zirconia or silicon carbide for hybrid abrasive formulations.
Recommended Grain Sizes
- General cutting discs: F16–F36
- Reinforced cutoff wheels: F30–F60
- Precision cutting tools: F80–F120
Special coatings and surface treatments available to enhance bond retention and cutting life.
