| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Fully softened condition for severe forming or for re-solution treatment; not a normal stock temper. | 50 | 105 | 27 | 28 HB | 58 % IACS |
Cooled from hot working and naturally aged | As-extruded press-quenched profile left to age at room temperature; used when maximum bendability/forming is needed before final ageing. | 70 | 130 | 20 | 45 HB | 50 % IACS |
Solution heat treated and naturally aged | Pick when profiles must be bent, roll-formed or stretch-formed before final artificial ageing to T6. | 90 | 160 | 20 | 52 HB | 46 % IACS |
Solution heat treated and under-aged | Under-aged compromise temper for profiles that still need appreciable bending/crimping after ageing. | 125 | 185 | 14 | 62 HB | 50 % IACS |
Cooled from hot working and artificially aged | Highest-productivity route: press-quench plus ageing oven — the standard temper for architectural window/door and trim profiles. | 155 | 195 | 10 | 65 HB | 55 % IACS |

What is 6360?
6360 is a lean Al-Si-Mg-Mn extrusion alloy (A96360, AlSiMgMn) developed for high press exit speeds while retaining the anodizing quality of 6060 and 6063. Supplied as T1, T4, T5, T6, T64, T66 and O profiles, the default condition gives 190 MPa yield, 230 MPa tensile, 11 % elongation, 75 HB, 200 W/m·K and 53 % IACS, with corrosion resistance rated 72. Strength is well below 6061 or 6082, service temperature is limited to about 150 °C, and thin sections in T6/T66 tolerate only generous bend radii. 6063 is the closest substitute where extrusion productivity is not the constraint. 6360 has a density of 2.7 g/cm³ (0.0975 lb/in³), lighter than 59% of aluminum grades. It melts at 600°C (1,112 °F). 6360 has a yield strength of 190 MPa (27.6 ksi) and a tensile strength of 230 MPa (33.4 ksi) — weaker than 52% of aluminum grades. Elongation at break is 11% and the elastic modulus is 69 GPa (10 Msi).

Working with 6360
Is 6360 easy to machine?
Machines easily in T5/T6 with sharp polished-flute carbide, high speed and generous coolant/lubricant; T4 and O are gummy and prone to built-up edge.
Can 6360 be welded?
Readily GMAW/GTAW welded with 4043 (crack-safe) or 5356 (stronger, better anodizing colour match); HAZ drops to near-T4 strength unless post-weld aged.
Can 6360 be formed, bent or molded?
Designed for very high extrusion exit speeds and thin architectural sections; bend and roll-form in T1/T4/T64, avoid tight radii in T6/T66.

6360 — frequently asked
What is 6360 used for?
6360 is typically used for architectural extrusions, window and door profiles and curtain wall sections. In short: high-speed extrusion alloy; anodizing-quality architectural grade; higher output than 6063.
What is the yield strength of 6360?
6360 has a typical yield strength of 190 MPa (27.6 ksi) and a tensile strength of 230 MPa (33.4 ksi) — weaker than 52% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is 6360 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 59% of aluminum grades). Machines easily in T5/T6 with sharp polished-flute carbide, high speed and generous coolant/lubricant; T4 and O are gummy and prone to built-up edge.
Can 6360 be welded?
Yes — weldability is rated excellent (85/100). Readily GMAW/GTAW welded with 4043 (crack-safe) or 5356 (stronger, better anodizing colour match); HAZ drops to near-T4 strength unless post-weld aged.

What is the maximum service temperature of 6360?
6360 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 6360-T6 and 6360-O?
T6 is the default condition — default stocked condition: full peak-aged strength with retained bright anodizing quality for load-bearing architectural and industrial profiles. O: fully softened condition for severe forming or for re-solution treatment; not a normal stock temper. Yield strength is 190 MPa in T6 versus 50 MPa in O.
How much does 6360 cost?
6360 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.
