Products Description

Brown Aluminum Oxide (BFAO) Abrasive Grit & Powder Supplier | NYTWO

Brown Fused Aluminum Oxide, also known as brown aluminum oxide, is a synthetic abrasive produced by fusing high-quality bauxite in an electric arc furnace at temperatures exceeding 2000°C. It is characterized by high toughness, excellent wear resistance, and cost-effectiveness, making it a primary choice for industrial grinding and surface treatment applications.

Why Choose Our Brown Fused Aluminum Oxide?

Exceptional Toughness

A TiO₂ content of 2-3% provides superior impact and crushing resistance, resulting in a longer operational life.

High Cost-Effectiveness

Offers a significant cost advantage over white fused aluminum oxide or silicon carbide in applications where high toughness is required.

Consistent Quality

Rigorous production controls ensure consistent performance and reliable results from batch to batch.

Common Applications

Abrasive Blasting

Effectively removes rust, old paint, and mill scale from metal surfaces, creating an ideal anchor profile for coatings.

Recommended Grit Sizes: F16 - F80

Abrasive Tool Manufacturing

Used in the production of grinding wheels and cutting discs, suitable for grinding high-tensile strength metals and cleaning welds.

Recommended Grit Sizes: F24 - F120

Refractories

Used as a robust aggregate in refractory bricks and castables, providing excellent high-temperature resistance and corrosion erosion.

Recommended Grit Sizes: 0-1mm, 1-3mm,3-5mm,46F,-200 Mesh

FAQ

Q: What is the main difference between Brown and White Fused Aluminum Oxide?

A: Brown Aluminum Oxide contains 2-3% TiO₂, giving it higher toughness and impact resistance, making it ideal for heavy-duty grinding and blasting. White Fused Aluminum Oxide has a higher purity (Al₂O₃ ≥99%), is harder but less tough, making it more suitable for precision grinding of hard, brittle materials.

Q: How do I select the right grit size?

A: Grit selection depends on the specific application: Coarse grits (F12-F30) are for rapid stock removal, medium grits (F40-F80) for general grinding and blasting, and fine grits (F100-F220) for finishing. Our engineers can recommend the optimal size based on your requirements.
