Beschreibung
Zusammenfassung:	Disclosed are improved thick wrought 7xxx aluminum alloy products, and methods for producing the same. The new 7xxx aluminum alloy products may realize an improved combination of properties, such as an improved combination of two or more of environmentally assisted crack resistance, strength, elongation, and fracture toughness, among other properties. The new 7xxx aluminum alloy products may include 5.5-6.5 wt. % Zn, 1.3-1.7 wt. % Mg, and 1.7-2.3 wt. % Cu. 本发明公开了改进的厚锻造7xxx铝合金产品及其生产方法。新型7xxx铝合金产品可实现性质的改进组合，如环境致裂抵抗性、强度、伸长率和断裂韧性等性质中的两种或更多种的改进组合。所述新型7xxx铝合金产品可以包含5.5-6.5重量％的Zn、1.3-1.7重量％的Mg和1.7-2.3重量％的Cu。
