Recommended Grit: F16 - F36

Abrasive Blasting

Scenario: Surface Preparation & Cleaning

Description: Efficiently removes rust, old paint, and scale, providing an ideal anchor profile for coatings.

Recommended Grit: F16 - F80

Refractories

Scenario: High-Performance Refractory Aggregate

Description: Used as an aggregate in casting coatings, refractory bricks, and castables, delivering excellent high-temperature resistance and anti-corrosion properties.

Recommended Grit: F24 - P80

Anti-Slip & Wear-Resistant Systems

Scenario: Wear-Resistant Flooring & Coatings

Description: Used in industrial flooring, non-slip decks, and wear-resistant coatings, providing lasting traction and abrasion resistance.

Recommended Grit: F30 - F60

Why Engineers Choose NYTWO's Brown Fused Alumina

Superior Toughness

TiO₂ content (2-3%) provides exceptional impact and crushing resistance, far exceeding white fused alumina, resulting in a longer operational life.

Consistent Quality

Strict grit size control (FEPA Standard F), ensuring high consistency between batches and stable, reliable processing results.

High Cost-Effectiveness

Offers better cost-effectiveness than white fused alumina or silicon carbide in applications requiring high toughness.

Global Compliance & Support

ISO 9001 certified. Complete SDS (Safety Data Sheet) and technical support provided.

Products Description

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

A: Brown Alumina (BFAO) is tougher and more impact-resistant due to its TiO₂ content, making it ideal for heavy-duty work on high-tensile strength materials. White Alumina (WFAO) is harder and purer (99%+ Al₂O₃), making it better for precision grinding of hard, brittle steels or where iron contamination is a concern.

Q: How do I choose the right grit size?

A: It depends on your application. Coarse grits (F12-F30) are for rapid stock removal. Medium grits (F40-F80) are for general grinding and blasting. Fine grits (F100-F220) are for finishing. Our engineers can help you select the optimal size.

Q: Do you provide samples?

A: Yes, we provide free samples for qualified businesses. Please use the sample request form.

Q: What packaging options are available?

A: Standard packaging is 25kg woven bags with inner plastic film. We also offer 1-ton jumbo bags and custom packaging to meet your needs.
