Zn; about 3.5-5.5%;
Mg: about 0.8-1.5%;
Si: less than about 1%;
Mn: no more than about 0.04%; and
Fe and other incidental impurities: less than about 0.30%.
2. An aluminum alloy according to claim 1 further comprising at least one grain refiner selected from the group consisting of boron, carbon and combinations thereof.
3. An aluminum alloy according to claim 2, wherein said at least one grain refiner includes boron in a range from about 0.0025 to about 0.05%.
4. An aluminum alloy according to claim 2, wherein said at least one grain refiner includes carbon in a range from about 0.0025 to about 0.05%.
5. An aluminum alloy according to claim 1 further comprising at least one anti-recrystallization agent selected from the group consisting of zirconium, scandium and combinations thereof,
6. An aluminum alloy according to claim 5 wherein said at least one anti-recrystallization agent includes zirconium in a range below 0.2%,
7. An aluminum alloy according to claim 5 wherein said at least one aπti-recrystallization agent includes scandium in a range below 0.3%. 8. An aluminum alloy according to claim 1 wherein said zinc is at a concentration of about 4.2 to 4.
8%,
9. An aluminum alloy according to claim 1 wherein said zinc is at a concentration of about 4.4 to 4.6%.
10. An aluminum alloy according to claim 1 wherein said magnesium is at a concentration of about 1.0 to 1,4%.
11. An aluminum alloy according to claim 10 wherein said magnesium is at a concentration of about 1.1 to 1.3%,
