Brown Fused Alumina for Die Casting
Improve the surface quality and durability of aluminum and zinc alloy castings through precise abrasive finishing.
Why Use BFA in Die Casting Finishing?
Die cast parts often have surface imperfections such as burrs, scale, or flash that require efficient finishing. Brown fused alumina (BFA) is an ideal media for abrasive blasting and cleaning due to its sharp grains, high hardness, and recyclability—ensuring clean surfaces without compromising dimensional accuracy.
- Effectively removes residues and sharp edges
- Preserves fine details and tolerances of complex castings
- Works well on aluminum, magnesium, and zinc alloy parts
Typical Applications in Die Casting
- Automotive engine housings and transmission cases
- Consumer electronics casings from zinc alloys
- Precision tool and die components
BFA finishing improves paint adhesion, coating performance, and functional surface quality in downstream processes.
Recommended Grit Sizes
- Deburring and flash removal: F24–F60
- Smoother surface finishing: F80–F120
- Surface texturing for coating: F150–F220
We can provide custom grit size recommendations based on your material type and blasting system.
