FAQ – Brown Fused Alumina Powder
We supply Black Fused Alumina Grit in a wide range of standard sizes, including FEPA F8–F220, JIS grit sizes, and selected mesh grades. Customized particle sizes can also be supplied according to specific application requirements.
Black Fused Alumina Grit is commonly used for sandblasting, surface preparation, deburring, grinding, cleaning, resin-bonded abrasives and anti-slip applications. Its high toughness and economical cost make it suitable for a wide range of industrial processing applications.
Yes. Black Fused Alumina is well suited for sandblasting and surface cleaning applications. Its angular grain shape provides effective cutting and material removal while maintaining good durability during abrasive blasting.
Black Fused Alumina generally has a lower Al₂O₃ content and is positioned as a more economical abrasive for blasting, polishing and general surface treatment. Brown Fused Alumina typically has a higher alumina content and stronger cutting performance, making it suitable for heavier grinding and material removal applications.
Black Fused Alumina Grit refers to coarser abrasive sizes, typically used for blasting, grinding, deburring and surface preparation. Black Fused Alumina Powder consists of finer particle sizes and is more suitable for fine grinding, polishing, lapping and applications requiring a smoother surface finish.
The recommended grit size depends on the required surface profile. Coarse grades such as F8–F36 are suitable for heavy rust removal and aggressive surface cleaning, while F40–F100 are commonly used for general surface preparation. Finer grades such as F120–F220 are better suited for fine finishing and precision blasting.
Yes. A Certificate of Analysis (COA) can be provided for applicable batches, including key chemical and physical parameters. Samples are also available for product testing and evaluation before bulk purchasing.
Standard packaging options include 25 kg bags and 1 MT reinforced FIBC big bags. Palletized and stretch-wrapped packaging is also available, and customized packaging can be arranged according to shipping and purchasing requirements.
