Definitions

  • FIG. 6A is a bar chart showing experimental results of flow- lengths and silicon content for alloys of some embodiments.
  • the aluminum alloy composition comprises iron (Fe) in an amount of, of about, of at most, or of at most about, 0.8 wt.%, 0.7 wt.%, 0.6 wt.%, 0.5 wt.%, 0.4 wt.%, 0.3 wt.%, 0.2 wt.%, 0.1 wt.%, 0.05 wt.%, or 0.01 wt.%, or any range of values therebetween.
  • iron (Fe) in an amount of, of about, of at most, or of at most about, 0.8 wt.%, 0.7 wt.%, 0.6 wt.%, 0.5 wt.%, 0.4 wt.%, 0.3 wt.%, 0.2 wt.%, 0.1 wt.%, 0.05 wt.%, or 0.01 wt.%, or any range of values therebetween.
  • the aluminum alloy composition comprises Al 2 Cu phases in, in about, in less than, or less than about, 2 wt.%, 1 .7 wt.%, 1.5 wt.%, 1.4 wt.%, 1.3 wt.%, 1.2 wt.%, 1.1 wt.%, 1 wt.%, 0.9 wt.%, 0.8 wt.%, 0.7 wt.%, 0.6 wt.%, 0.5 wt.%, 0.45 wt.%, 0.4 wt.%, 0.35 wt.%, 0.3 wt.%, 0.25 wt.%, 0.2 wt.%, 0.15 wt.%, 0.1 wt.%, 0.05 wt.%, 0.04 wt.%, 0.03 wt.%, 0.02 wt.%, 0.01 wt.%, 0.008 wt.%, 0.005 wt.% or 0.00
  • FIG. 3A is a plot of bend angles and ⁇ -aluminum volume fractions for alloys
  • FIG. 3B is a plot of bend angles and magnesium/nickel content for alloys of some embodiments.
  • bend angle of an alloy is, is about, is at least, or is at least about, 15°, 20°, 23°, 25°, 30°, 35°, 40°, or 50°, or any range of values therebetween. In some embodiments, bend angle is, or is about, 15°, 20°, 23°, 25°, 30°, 35°, 40°, 50° or 60°, or any range of values therebetween. In some embodiments, the bend angle is measured at a 3 mm section thickness. In some embodiments, the bend angle is measured using the VDA238-100 evaluation standards. In some embodiments,
  • FIG. 6A show's that an alloy composition with 7.5 wt.% silicon had a flow length of about 1.4 meters, an alloy composition with 8.5 wt.% silicon had a flow length of about 1.45 meters, and an alloy composition with 9.5 wt.% silicon had a flow length of about 1.45 meters.
  • silicon ranges for the alloy composition should be maintained over 6 wt.% to achieve advantageous flow lengths, but could be less than 11 wt.% fe.g. 8 wt.% or 7.5 wt.%) to minimize eutectic silicon phase’s effect on reducing ductility.
  • the alloy of FIG. 9B shows a decrease in plate morphologies, and generally shows feature 906 of AlFeSi(Mn + V) phase with globular morphology more favorable for ductility, which was found to include greater than 1.2 wt.% V.
  • vanadium and manganese may be used to reduce iron impurity solubility and stabilize AlFeSi(Mn,V) phases that have a rounded morphology. This allows the alloy to maintain high ductility performance with higher tolerances of Fe.
