摘要

变形热处理的7xxx合金比2xxx系列合金对沉淀硬化更敏感，可以达到更高的强度水平，接近690 MPa (100 ksi)的抗拉强度。本文综述了7xxx铝合金的主要冶金、性能和应用。阐述了7050铝合金在室温下的自然时效特性以及7xxx系列常用合金之间的关系。

7xxx Aluminum Alloy Datasheets

Wrought heat treatable 7xxx alloys are more responsive to precipitation hardening than the 2xxx series alloys and can achieve higher strength levels, approaching tensile strengths of 690 MPa (100 ksi). This article provides an overview of key metallurgy, properties, and applications of the 7xxx aluminum alloy. It also illustrates the natural aging characteristics of 7050 aluminum sheet alloys at room temperature and relationships among commonly used alloys in the 7xxx series.
