What type of white corundum is used for sandblasting aluminum?
White corundum is an artificial abrasive with aluminum oxide as the main component.
Due to its high hardness, wear resistance, resistance to acid and alkali corrosion, and high temperature resistance, it is suitable for sandblasting aluminum materials.
2. Model selection of white corundum
White corundum particle size sand: Aluminum material required for general sandblasting, such as 8#-220# (or 8 mesh-220 mesh) white corundum. These models provide moderate blasting effects and cutting forces.
Micropowder: suitable for aluminum materials with high precision and finer sandblasting effects, such as 240#-10000# (or 240 mesh-10000 mesh) white corundum. Make the aluminum surface smoother.
Other considerations:
Hardness: White corundum has high hardness and strong cutting power, and can quickly remove impurities such as dirt, pollutants, rust, and old coatings on the aluminum surface.
Wear resistance: White corundum has high wear resistance and can maintain a long service life during the sandblasting process.
