Aluminum sheet with enhanced formability and an aluminum container made from aluminum sheet

1. A method comprising:

obtaining an aluminum sheet comprising a 3xxx or a 5xxx alloy; wherein the aluminum sheet has 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 wherein the aluminum sheet has a thickness of 0.006 inch to 0.030 inch;

drawing and ironing the aluminum sheet to form an aluminum container having a dome;

necking the aluminum container to reduce a diameter of a portion of the aluminum container to form a bottle; and

finishing the bottle so as to result in the bottle configured to accept a closure.

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, 3x04 or 3x05.

7. The method of claim 1 , wherein the aluminum sheet comprises AA 3104.

8. The method of claim 1 , further comprising expanding a section of the portion of the aluminum container having the reduced diameter.

9. The method of claim 8 , wherein the section has a length and the length is at least 0.3 inches.

10. The method of claim 9 , wherein the length is at least 0.4 inches.

11. The method of claim 1 , wherein the aluminum sheet is a 3xxx alloy.

12. The method of claim 1 , wherein the 5xxx alloy is a 5043 alloy.
