    摘要： 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.

    摘要： Aluminum and aluminum alloy microstructures that are adapted for improved performance during shaping and forming production processes. Lower relative ratios of alpha fibers, particularly low-end alpha fibers, to beta fibers promotes improved formability of aluminum sheet or blanks without negatively impacting material strength. Beta fibers with higher relative ratios of S and Copper texture components improve formability and produce fewer and more uniform distortions during production. The resulting improvements in quality allow for cupping, drawing, wall ironing, shaping, and necking processes to be carried out faster and with reduced rates of spoilage.

    摘要翻译： 铝和铝合金微观结构适合在成型和成型生产过程中改进性能。 α纤维（特别是低端α纤维）相对于β纤维的相对比率的降低促进了铝板或毛坯的可成形性的提高，而没有负面影响材料强度。 具有较高的S和铜织构组分的相对比率的β纤维改善成形性并在生产期间产生更少且更均匀的变形。 由此产生的质量改进可以使拔罐，拉拔，壁熨烫，成型和颈缩过程更快速并降低腐败率。

    摘要： Disclosed is an aluminum alloy for aluminum bottle applications, including methods of producing highly shaped aluminum products, such as bottles or cans, comprising the aluminum alloy. In some cases, the aluminum alloy has improved high strain rate formability at elevated temperatures and improved earing, which results in reduced spoilage rates. In one non-limiting example, the disclosed alloys have stable values greater than or equal to 0.035, where ε stable = ε F - ε S and ε S represents the strain at which work hardening stage IV starts and ε F represents the strain at which diffuse necking ends. In some cases, the disclosed alloys have an earing balance from about -3.5 % to about 2 % and a mean earing of less than or equal to 5.5 %.
