This high-strength wrought alloy, composed primarily of aluminum, zinc, magnesium, and copper, exhibits a unique combination of characteristics that distinguish it from other aluminum alloys. For instance, its tensile strength is comparable to many steels, while maintaining a significantly lower density. This specific blend of elements contributes to exceptional fatigue resistance and hardness, making it suitable for demanding applications.
The superior strength-to-weight ratio of this material has historically driven its adoption in aerospace applications, where weight savings are critical. Its resilience under stress and resistance to cracking further enhance its suitability for structural components subject to cyclic loading. These benefits extend beyond aerospace, finding utility in high-performance sporting equipment, automotive parts, and specialized tooling where durability and lightweight construction are paramount.
