Abstract
Disclosed are alloys for anodized-quality aluminum sheets with improved surface quality, and methods for making these sheets. The alloys are designed to minimize the formation of cathodic intermetallic particles that result in surface streaks of anodized sheet products formed from the alloys. Further, the alloys allow the incorporation of recycled scrap aluminum in anodized-quality sheets.
