In the manufacturing process of automotive parts, sandblasting is a key link. Sandblasting can remove impurities, oxide layers and old coatings, increase surface roughness, improve coating adhesion and durability, and improve the appearance of parts. Brown corundum can provide more effective and uniform abrasive effects during sandblasting due to its high hardness and uniform particle shape.

Brown corundum has a wide range of applications in sandblasting of automotive parts. For example, it can be used to sandblast key parts such as engine cylinder heads, crankshafts, gears, and brake systems. Brown corundum sandblasting can effectively remove surface stains, oxide layers and old coatings, and improve coating adhesion and durability.
Advantages of brown corundum sandblasting:
1. Its hardness is higher than other sandblasting materials, which can more effectively remove surface stains and oxide layers.
2. The high particle density of brown corundum can provide stronger impact and quickly remove surface stains and old coatings.
3. It has good wear resistance and can maintain a long service life during sandblasting, reducing the number of replacements and costs.
4. The particle shape of brown corundum is uniform, which can provide uniform sandblasting effect and avoid uneven surface treatment effect.
Research shows that the use of brown corundum for sandblasting can significantly improve the adhesion, durability and appearance quality of the coating. In addition, the service life of brown corundum sandblasting is also significantly better than other sandblasting materials, reducing production costs.
