ALUMINUM ALLOY PRODUCTS

摘要

The aluminum alloy product of an embodiment of the present invention includes a pair of outer regions and an inner region positioned between the outer regions. A first concentration of eutectic forming alloying elements in the inner region is less than a second concentration of eutectic forming alloying elements in each of the outer regions. Further, the aluminum alloy product has a delta r value of 0 to 0.10. The delta r value is calculated as follows: Absolute Value [(r_L+r_LT−2*r_45)/2] and the r_L is an r value in a longitudinal direction of the aluminum alloy product, the r_LT is an r value in a transverse direction of the aluminum alloy product, and the r_45 is an r value in a 45 degree direction of the aluminum alloy product.

1. An aluminum alloy product comprising:
a pair of outer regions and an inner region positioned between the outer regions; wherein a first concentration of eutectic forming alloying elements in the inner region is less than a second concentration of eutectic forming alloying elements in each of the outer regions; wherein the aluminum alloy product has a delta r value of 0 to 0.10; wherein the delta r value is calculated as follows:
Absolute Value [(r_L+r_LT−2*r_45)/2]wherein r_L is an r value in a longitudinal direction of the aluminum alloy product;wherein r_LT is an r value in a transverse direction of the aluminum alloy product; and wherein r_45 is an r value in a 45 degree direction of the aluminum alloy product.
