1. An aluminum alloy product comprising: a first-product portion;a central-product portion; anda second-product portion;wherein the central-product portion is disposed between the first-product portion and the second-product portion;wherein the first-product portion, the central-product portion, and the second-product portion each have particulate matter;wherein the central-product portion has a higher concentration of particulate matter than each of the first-product portion and the second-product portion, wherein the particulate matter is selected from the group consisting of aluminum oxide, boron carbide, silicon carbide and boron nitride, and the aluminum alloy product has a thickness ranging from between about 0.004 inches to about 0.25 inches, andwherein the aluminum alloy product is selected from the group consisting of a single-cast aluminum alloy strip, a single-cast aluminum alloy sheet, a single-cast aluminum alloy panel, a single-cast aluminum alloy slab, a single-cast aluminum alloy foil, a single-cast aluminum alloy wire, a single-cast aluminum alloy rod, and a single-cast aluminum alloy bar. 2. The aluminum alloy product of claim 1, wherein a volume of the central-product portion has up to about 70 volume percent aluminum oxide particles. 3. The aluminum alloy product of claim 1, wherein the thickness range of the aluminum alloy product is from 0.08 inches to 0.25 inches. 4. The aluminum alloy product of claim 1, wherein about 70%, by volume, of the particulate matter is in the central-product portion, about 10%, by volume, of the particulate matter is in the first-product portion, and about 10%, by volume, of the particulate matter is in the second-product portion. 5. An aluminum alloy product comprising: a first-product portion;a second-product portion; anda central-product portion disposed between the first shell and the second shell; wherein the first-product portion, the second-product portion, and the central-product portion form the single-layered aluminum alloy product;wherein the first-product portion, the central-product portion, and the second-product portion each have particulate matter, and the particulate matter is distributed across the first-product portion, the central-product portion, and the second-product portion in a concentration gradient;wherein the central-product portion has a higher concentration of the particulate matter than each of the first-product portion and the second-product portion;wherein the particulate matter is selected from the group consisting of aluminum oxide, boron carbide, silicon carbide and boron nitride;wherein the aluminum alloy product has a thickness ranging from between about 0.004 inches to about 0.25 inches; andwherein the aluminum alloy product is selected from the group consisting of a single-cast aluminum alloy strip, a single-cast aluminum alloy sheet, a single-cast aluminum alloy panel, a single-cast aluminum alloy slab, a single-cast aluminum alloy foil, a single-cast aluminum alloy wire, a single-cast aluminum alloy rod, and a single-cast aluminum alloy bar.
