Abstract

See full text

Provided herein are new aluminum alloys comprising Ca, Mg and/or Zn and new coated aluminum alloys comprising surface layers (e.g., coatings) comprising Ca, Mn, Zn, and/or Ni that can be used in aluminum alloy products, such as clad layers. Also provided are methods of making these aluminum alloys, coated aluminum alloys, and clad layers, as well as clad products. These alloys, coated alloys, clad layers, and products possess a combination of strength and other key attributes, such as corrosion resistance, formability, and applicability of paint line pretreatments. The materials can be used in a variety of applications, including automotive, transportation, and electronics applications.
