High-Performance Aluminum Oxide Blasting Media (Brown Fused Alumina)

Brown Fused Alumina (BFA) is a synthetic abrasive made from bauxite melted in a high-temperature electric arc furnace. Its primary component is aluminum oxide (Al₂O₃). With its high hardness, excellent toughness, and wear resistance, BFA is one of the most commonly used abrasives for industrial sandblasting.

• Mohs Hardness: Approx. 9

1. Wear Proper Protective Equipment

Recommended protective equipment:

• Sandblasting helmet

• Dust mask or respirator

• Safety goggles

• Protective gloves

2. Keep Away from Moisture

Exposure to moisture may cause Brown Fused Alumina to:

• Clump together

• Clog the blasting nozzle

• Reduce media flow

Store in a cool, dry place and keep the abrasive media dry.
