摘要

Aluminium alloy 6082-T6 (AA6082-T6) is one of the highest-strength alloys within the Al–Mg–Si (6xxx) series. It is widely used in structural, marine, transportation, and corrosion-critical applications due to its high strength-to-weight ratios, excellent extrudability, and good corrosion resistance. The review provides a comprehensive and integrated assessment of the current state of research on AA6082-T6, with particular emphasis on the interconnections between its composition, microstructure, and resulting properties. The roles of alloying elements, precipitation-hardening mechanisms, and thermomechanical processing routes in governing mechanical performance are critically examined.

The anodizing behaviour of AA6082-T6 is reviewed in detail, and the resulting improvements in surface hardness and corrosion performance are discussed. Corrosion behaviour in chloride-rich and high-alkaline environments is analysed with respect to passive film stability, micro-galvanic interactions, and the influence of secondary phase particles. Sustainability and life-cycle considerations are incorporated to assess the long-term viability of AA6082-T6 relative to conventional structural materials. By synthesizing existing knowledge and identifying key research gaps, this review aims to support improved alloy design, surface engineering strategies, and predictive modelling frameworks. These insights facilitate the broader adoption of AA6082-T6 in next-generation structural and corrosion-critical applications.
