Brown Fused Alumina for Metal Finishing Applications
Explore how our high-purity BFA enhances surface preparation, grinding, and polishing in metal processing industries.
Why Choose Brown Fused Alumina for Metal Finishing?
Brown fused alumina (BFA) is a preferred abrasive material for metal finishing applications due to its exceptional hardness, thermal stability, and chemical resistance. It is ideal for abrasive blasting, grinding, deburring, and polishing processes across a wide range of metals.
- High durability and toughness for extended abrasive life
- Consistent grit size for uniform surface finishes
- Excellent performance in both dry and wet blasting systems
Typical Applications in Metal Processing
Brown fused alumina is widely used in the following metalworking applications:
- Abrasive blasting of steel surfaces before coating
- Polishing stainless steel and aluminum components
- Deburring machined metal parts
- Surface conditioning of cast iron and non-ferrous alloys
- Tool sharpening and edge profiling
- Weld seam cleaning and finishing
These applications improve product durability and coating adhesion, crucial for industries such as automotive, aerospace, and fabrication.
Recommended Grit Sizes
For optimal metal finishing results, we recommend the following grit ranges:
- Coarse finishing: F16–F36
- Intermediate smoothing: F46–F80
- Fine polishing: F100–F220
You can find detailed specifications on our BFA powder page for fine applications.
