Alloy comparison
6063-T5 Aluminum vs 6082-T6 Aluminum
extrusion finish vs structural strength
Side-by-side handbook properties for preliminary material selection. Green values mark the preferable metric for that row (higher strength, lower density, better fabrication rating).
6063-T5 Aluminum
6xxx · ASTM B221 / EN AW-6063

Quick selection guide
- Choose 6063-T5 Aluminum when you prioritize extrusions and window frames, and welding is acceptable.
- Choose 6082-T6 Aluminum when you prioritize bridges and trusses (higher yield: 310 vs 170 MPa).
- Weight difference on a 1 m² × 10 mm plate: 0.10 kg (6063-T5 Aluminum is lighter).
