In some embodiments of present disclosure, a method includes: obtaining an aluminum sheet comprising a 3xxx or a 5xxx alloy having a tensile yield strength as measured in the longitudinal direction of 27-33 ksi and an ultimate tensile strength; wherein the ultimate tensile strength minus the tensile yield strength is less than 3.30 ksi (UTS-TYS<3.30 ksi); and forming a container having a dome from the aluminum sheet. 1. A method comprising:obtaining an aluminum sheet comprising a 3xxx or a 5xxx alloy having a tensile yield strength as measured in the longitudinal direction of 27-33 ksi and an ultimate tensile strength; wherein the ultimate tensile strength minus the tensile yield strength is less than 3.30 ksi (UTS-TYS<3.30 ksi); andforming a container having a dome from the aluminum sheet.2. The method of claim 1 , wherein the tensile yield strength as measured in the longitudinal direction is 28-32 ksi.3. The method of claim 1 , wherein the tensile yield strength as measured in the longitudinal direction is 28.53-31.14 ksi.4. The method of claim 1 , wherein the ultimate tensile strength minus the tensile yield strength is 2.90-3.30 ksi.5. The method of claim 1 , wherein the ultimate tensile strength minus the tensile yield strength is 2.99-3.30 ksi.6. The method of claim 1 , wherein the aluminum sheet comprises one of AA: 3x03 claim 1 , 3x04 or 3x05.7. The method of claim 1 , wherein the aluminum sheet comprises AA 3104.8. The method of claim 1 , wherein the container is a bottle.9. The method of claim 1 , further comprising expanding a section of the portion of the container having a reduced diameter.10. The method of claim 9 , wherein the section has a length and the length is at least 0.3 inches.11. The method of claim 10 , wherein the length is at least 0.4 inches. This patent application is a continuation of U.S. Non-Provisional patent application No. 14/701,154 filed Apr. 30, 2015, which claims priority to U.S. Provisional Patent Application No. 61/986,692 ...
