Used for heat exchangers, decorative applications. • 5052-H32: Excellent corrosion resistance, especially to salt water. Good weldability and moderate strength. • 2024-T3: High strength, primarily used in aerospace applications. Poor weldability. • 7075-T6: Ultra-high strength, used in high-stress applications. Not recommended for welding. | ASTM B210 (Drawn Tube), ASTM B241 (Extruded Tube/Pipe), ASTM B491 (Extruded Round Tube) |

| Length | Standard random lengths or cut-to-length. | / | |
| Mechanical Properties | Ultimate Tensile Strength (UTS) | The maximum stress the tube can withstand. Example (6061-T6): 38 ksi (262 MPa) min Example (3003-H18): 29 ksi (200 MPa) min Example (5052-H32): 31 ksi (214 MPa) min | ASTM E8/E8M |
| Tensile Yield Strength (TYS) | The stress at which the bar begins to deform plastically. Example (6061-T6): 38 ksi (262 MPa) min Example (2024-T3): 47 ksi (324 MPa) min Example (7075-T6): 69 ksi (476 MPa) min | ASTM E8/E8M | |
| Elongation at Break | The stress at which the tube begins to deform plastically. Example (6061-T6): 35 ksi (241 MPa) min Example (3003-H18): 27 ksi (186 MPa) min Example (5052-H32): 25 ksi (172 MPa) min | ASTM E8/E8M | |
| Hardness | Typical (6061-T6): Brinell 95 HB | ASTM E10 | |
| Burst Pressure | The maximum internal pressure the tube can withstand before failure. Calculated using Barlow's formula: P = 2 * S * t / D, where S is hoop stress, t is min wall thickness, D is OD. | / | |
| Physical & Chemical Properties | Density | Standard Value: 2.70 g/cm³ (0.098 lb/in³) | / |
| Modulus of Elasticity | Standard Value: 10,000 ksi (69 GPa) | / | |
| Chemical Composition | Elemental limits as defined by the alloy specification. | ASTM B210, B241 | |
| Thermal Conductivity | Example (6061-T6): 167 W/m·K | / | |

| Fabrication & Performance | Weldability | Rating: • 6061, 5052, 3003: Excellent (using GTAW/TIG or GMAW/MIG with appropriate filler like 4043 or 5356). • 2024, 7075: Poor (crack-sensitive). | AWS D1.2 |
| Machinability | Rating (6061-T6): Good. Rating (2011-T3): Excellent (Free-machining alloy, but less common in tube form). | / | |
| Bendability / Formability | The ability to be bent without kinking or cracking. Heavily dependent on alloy, temper, and the ratio of OD to Wall Thickness. Annealed (O) tempers are best. | / | |
| Corrosion Resistance | Generally excellent for most alloys. 5052 is particularly good for marine environments. | / | |
