Annealed | Softest condition for deep drawing or severe bending before heat treatment. | 60 | 130 | 28 | 35 HB | 55 % IACS |

What is 6008?
6008 is a vanadium-modified Al-Mg-Si (6000 series) heat-treatable extrusion alloy, registered as A96008 / AlSiMgV. Engineers specify it where architectural profiles must run at high extrusion speed yet still reach 235 MPa yield and 270 MPa tensile with 12 % elongation, 90 HB and 190 W/m·K; it is supplied as extruded profiles, tube and bar in O, T4, T5, T6, T61, T64 and T66. Service is limited to about 150 °C, formability is moderate (T6 needs ≥3t bend radii) and fusion welding softens the heat-affected zone toward T4 strength. Where extrusion speed matters less than strength, 6061 or 6082 is the usual alternative. 6008 has a density of 2.7 g/cm³ (0.0975 lb/in³), lighter than 59% of aluminum grades. It melts at 585°C (1,085 °F). 6008 has a yield strength of 235 MPa (34.1 ksi) and a tensile strength of 270 MPa (39.2 ksi) — stronger than 61% of aluminum grades. Elongation at break is 12% and the elastic modulus is 69 GPa (10 Msi).

Working with 6008
Is 6008 easy to machine?
Machines freely in T5/T6 with sharp polished-flute carbide, high speed and generous coolant; T4/O tempers are gummy and tend to build up on edges.
Can 6008 be welded?
Readily GMAW/GTAW welded with 4043 (crack resistance) or 5356 (strength/anodizing match); expect HAZ softening to near-T4 levels unless post-weld aged.
Can 6008 be formed, bent or molded?
Extrudes at high speed thanks to the V-modified chemistry; form and hem in T4/T64, avoid tight-radius bending in T6 (use ≥3t radius).

What surface finishes work on 6008?
Excellent clear and colour anodizing and powder coating; mechanical polishing and brightening are good, chemical brightening acceptable due to low Cu.

6008 — frequently asked
What is 6008 used for?
6008 is typically used for window and door frames, curtain-wall mullions and transoms, architectural extrusions and trim profiles, glazing bars and thermal-break profiles, handrail and balustrade sections and solar module frames. In short: high-speed extrusion 6000 series; low-copper, anodizes cleanly; medium strength, weldable.
What is the yield strength of 6008?
6008 has a typical yield strength of 235 MPa (34.1 ksi) and a tensile strength of 270 MPa (39.2 ksi) — stronger than 61% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is 6008 easy to machine?
Reasonably — machinability is rated good (60/100, worse than 51% of aluminum grades). Machines freely in T5/T6 with sharp polished-flute carbide, high speed and generous coolant; T4/O tempers are gummy and tend to build up on edges.
Can 6008 be welded?
Yes — weldability is rated very good (75/100). Readily GMAW/GTAW welded with 4043 (crack resistance) or 5356 (strength/anodizing match); expect HAZ softening to near-T4 levels unless post-weld aged.
What surface finishes work on 6008?

Can 6008 be formed, bent or molded?
Extrudes at high speed thanks to the V-modified chemistry; form and hem in T4/T64, avoid tight-radius bending in T6 (use ≥3t radius).
What is the maximum service temperature of 6008?
6008 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 6008-T6 and 6008-O?
T6 is the default condition — default stocked condition: maximum strength for structural window/curtain-wall and automotive profiles. O: softest condition for deep drawing or severe bending before heat treatment. Yield strength is 235 MPa in T6 versus 60 MPa in O.
How much does 6008 cost?
6008 is a standard-cost aluminum ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
