Surface Treatment of Automotive Aluminum Sheets
Adds suitable surface properties to aluminum sheets
Automotive aluminum sheets require surface properties such as spot weldability, adhesive durability, paintability, and corrosion resistance. Kobe Steel proposes surface treatment solutions according to the properties required by our customers. We can provide aluminum sheets with Ti/Zr treatment, electron discharge texturing (EDT) surface and dry lubricant.
Surface treatments
- Removal of oxide film on the surface of aluminum sheets and application of conversion coating improves spot weldability, adhesive durability, and paintability.
Surface texture
- Aluminum sheets surface texture is controlled by processing the surface of milling rolls.
Lubricant
- Lubricant improves rust resistance during storage and lubricity when forming.
