EN AW-6082 vs EN AW-7075
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-6082
3.2315
High-strength structural aluminium alloy in the Al-Mg-Si family. One of the strongest 6xxx series alloys due to manganese addition. Replaced 6061 in many European applications. Used for trusses, bridges, cranes, transport, scaffolding, and marine applications. Heat treatable (T6/T651).
EN AW-7075
3.4365
THE aerospace aluminum — Al-Zn5.6-Mg-Cu precipitation-hardened to the highest strength of any common aluminum alloy. T6 strength rivaling mild steel at 1/3 the density. Poor weldability and corrosion resistance vs 5xxx/6xxx. Used for aircraft wing skins, fuselage frames, high-stress structural components, and competitive cycling/climbing equipment. Often Alclad for corrosion protection.
