Brown Fused Aluminum Oxide
Brown Fused Aluminum Oxide (BFA) is a robust abrasive used in sandblasting for surface preparation, stripping away paint, rust, and contaminants to enhance coating adhesion. Its aggressive nature also makes it suitable for etching and texturing surfaces for aesthetic finishes or improved mechanical bonding. In addition, BFA is effective for deburring, smoothing out sharp edges on metal parts. Known for its hardness and high density, BFA is ideal for blasting metals, glass, ceramics, and stone. It is highly valued for its durability and recyclability, capable of being reused in blasting processes before replacement is necessary.
