Products Description
Brown Fused Alumina (BFA) is a popular abrasive material used in sandblasting due to its excellent properties, such as high hardness, toughness, and thermal stability. BFA is available in various grit sizes, which determine the coarseness of the abrasive. Here are some typical grit sizes of BFA for sandblasting:
Coarse Grit: BFA grit sizes of 12-24 mesh (large grit) and 24-60 mesh (medium grit) are commonly used for heavy-duty sandblasting applications, such as removing thick coatings, corrosion, and surface contaminants.
Medium Grit: BFA grit sizes of 60-120 mesh (fine grit) and 120-180 mesh (very fine grit) are suitable for general sandblasting applications, such as preparing surfaces for painting or removing light coatings and rust.
Fine Grit: BFA grit sizes of 180-240 mesh (extra fine grit) and 240-360 mesh (ultra-fine grit) are used for delicate sandblasting applications, such as etching glass or polishing metals.
When selecting the grit size of BFA for sandblasting, it is important to consider the surface material being blasted, the desired surface finish, and the blasting equipment being used. Using too coarse a grit can damage the surface, while using too fine a grit can result in a surface finish that is too smooth for certain applications.
