Aluminum 6061-T6: General-Purpose Structural Al-Mg-Si Alloy — Weldable, Corrosion-Resistant vs EN AW-6082-T6: European Medium-Strength Structural Aluminum Alloy
Side-by-side engineering comparison of Aluminum 6061-T6: General-Purpose Structural Al-Mg-Si Alloy — Weldable, Corrosion-Resistant (ASTM B209 / ASTM B308 / AMS 4027) and EN AW-6082-T6: European Medium-Strength Structural Aluminum Alloy (EN 755-2). Compare mechanical properties, chemical composition, density, yield strength, international equivalents, and typical applications to select the right material for your project.
Quick Verdict
6061-T6 is the standard general-purpose structural aluminum alloy with 276 MPa yield, excellent weldability, and good corrosion resistance — ideal for frames, extrusions, and machined components. 6082-T6 offers 310 MPa yield (12% higher) with superior corrosion resistance and is the preferred structural alloy in European standards for marine applications, bridges, and high-stress structural components. 6082 is less extrudable than 6061 and more difficult to machine.
