Abstract: 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.

Abstract translation: 本发明实施例的铝合金制品包括一对外部区域和位于外部区域之间的内部区域。 内部区域中的共晶形成合金元素的第一浓度小于每个外部区域中的共晶形成合金元素的第二浓度。 此外，铝合金制品的δr值为0至0.10。 Δr值的计算如下：绝对值[（r_L + r_LT-2 * r_45）/ 2]，r_L是铝合金制品的纵向的r值，r_LT是横向的r值 铝合金制品的方向，r_45是铝合金制品的45度方向的r值。
