Abstract
New 6xxx aluminum alloys are disclosed. The new 6xxx aluminum alloys may include 1.05-1.50 wt. Mg, 0.60-0.95 wt. % Si, where the (wt. % Mg)/(wt. % Si) is from 1.30 to 1.90, 0.275-0.50 wt. % Cu, and from 0.05 to 1.0 wt. % of at least one secondary element, wherein the secondary element is selected from the group consisting of V, Fe, Cr, Mn, Zr, Ti, and combinations thereof.
Claims20
A 6xxx aluminum alloy comprising:
- (a) 1.05-1.50 wt. % Mg;
- (b) 0.60-0.95 wt. % Si;
- wherein (wt. % Mg) / (wt. % Si) is from 1.30 to 1.90;
- (c) 0.35-0.50 wt. % Cu;
- (d) up to 0.25 wt. % V;
- (e) up to 0.50 wt. % Mn;
- (f) up to 0.40 wt. % Cr;
- (g) up to 0.25 wt. % Zr;
- (h) up to 0.80 wt. % Fe;
- (i) up to 0.10 wt. % Ti;
- wherein at least one of V, Cr, Mn and Zr is present, and wherein the combined amount of V, Cr, Mn, and Zr in the 6xxx aluminum alloy is from 0.15 to 0.80 wt. %;
- (j) the balance being aluminum and other elements, wherein each one of the other elements does not exceed 0.10 wt. % in the 6xxx aluminum alloy, and wherein the total of the other elements is not more than 0.35 wt. % in the 6xxx aluminum alloy;
- and
- wherein the 6xxx aluminum alloy is in the form of a rolled sheet or plate product, and wherein, in the T6 temper, the rolled sheet or plate product realizes a longitudinal tensile yield strength of from 48 to 55 ksi and an elongation of from 8 to 14%.
