6005A-T6

Medium-strength structural extrusion alloy: 225 MPa proof and 270 MPa tensile for open profiles up to 5 mm.

Between 6063 and 6082: stronger than 6060/6063 but extrudes into more complex and thinner sections than 6082 — railway and bus structures, masts, platforms. Open and hollow profiles have different minimums.

Missing on purpose: a value appears here only once a public source states it.

Sources here are public pages that reproduce EN 755-2. For design and acceptance, the standard edition named in your specification and the inspection certificate (EN 10204 3.1) of the delivered product take precedence. Design factors are recommended values; your National Annex may set others.
