Commercially pure aluminum (99.5% Al minimum). Excellent corrosion resistance, highest thermal and electrical conductivity among Al alloys, and outstanding formability. Low strength (UTS ~100 MPa annealed) limits structural use. Non-heat-treatable — strengthened only by cold work (H14/H24 tempers). Used for chemical processing equipment, food packaging foil, reflectors, heat exchangers, electrical busbars, capacitor foils, and architectural cladding/roofing. The baseline aluminum for conductivity applications.

Heat-treatable Al-Cu-Mg alloy (Duralumin family). Higher strength than 6xxx series in T4 condition (UTS ~430 MPa) with excellent machinability. Not suitable for welding due to Cu content. Limited corrosion resistance — usually anodized or clad. Standard material for turned parts, screw machine products, fittings and structural components requiring high strength. One of the original aerospace aluminum alloys.

The most extruded aluminum alloy in Europe — optimized for complex thin-walled extrusion profiles. Lower Mg+Si content than 6063/6082 provides excellent extrudability at moderate strength (UTS ~215 MPa T6). Good corrosion resistance, anodizability (decorative quality), and weldability. The default material for window/door frames, curtain wall mullions, railing systems, heat sinks, LED lighting profiles, and general architectural extrusions. EN AW-6063 is the closest ASTM equivalent.
