AA 6110 · UNS A96110 · EN AW-6110, AW 6110
6110 (EN AW-6110/6110A) is a heat-treatable Al-Mg-Si-Cu-Mn wrought alloy in which higher Si and Mg plus 0.2–0.7% Cu give T6 strength clearly above 6061 and 6082.
6110 tempers and conditions
6110 is supplied in 6 conditions, soft to hard.
Compare all 6 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Fully annealed for maximum cold formability or before re-solution treating; strength is low. | 70 | 135 | 26 | 40 HB | 47 % IACS |
Solution heat treated and naturally aged | Choose when parts must be stamped, bent or hemmed before a final paint-bake/T6 age to reach full strength. | 140 | 250 | 22 | 70 HB | 37 % IACS |
Solution heat treated and overaged (stabilized) | Over-aged for improved corrosion/IGC resistance and thermal stability, trading roughly 10 % of T6 strength. | 295 | 330 | 14 | 100 HB | 44 % IACS |
Cooled from hot working and artificially aged | Press-quenched extrusions aged without a separate solution treatment — lower cost and less distortion, ~10–15 % below T6 strength. | 300 | 340 | 10 | 105 HB | 42 % IACS |
T6, stress relieved by stretching | T6 properties with residual stress removed by controlled stretching — pick for plate or bar that will be heavily machined to tight tolerance. | 355 | 385 | 12 | 116 HB | 41 % IACS |
Solution heat treated and artificially aged | Standard supply condition: peak strength for automotive forgings, suspension parts and high-strength machined components. | 360 | 390 | 12 | 118 HB | 41 % IACS |
What is 6110?
6110 (EN AW-6110/6110A) is a heat-treatable Al-Mg-Si-Cu-Mn wrought alloy in which higher Si and Mg plus 0.2–0.7% Cu give T6 strength clearly above 6061 and 6082. It is used for automotive chassis forgings, extruded structural sections and high-strength machined parts, and it keeps the 6000-series family's good extrudability, forgeability and anodizing response. The copper addition reduces corrosion resistance — particularly intergranular corrosion sensitivity — and weldability relative to 6063 and 6005A, and quench and ageing practice must be tightly controlled. Use 6082-T6 where weldability or corrosion resistance matters more than peak strength. 6110 has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 580°C (1,076 °F). 6110 has a yield strength of 360 MPa (52.2 ksi) and a tensile strength of 390 MPa (56.6 ksi) — stronger than 84% of aluminum grades. Elongation at break is 12% and the elastic modulus is 70 GPa (10.2 Msi).

Working with 6110
Is 6110 easy to machine?
Machines very well in T6 with polished-flute carbide, high speed and flood coolant or MQL; sharp rake and chip breakers avoid the gummy chips seen in T4.
Can 6110 be welded?
MIG/TIG weldable with 4043 (crack resistance) or 5356 (strength/anodizing match); HAZ drops to near-T4 strength, so re-solution + age or design joints away from peak stress.
Can 6110 be formed, bent or molded?
Extrudes and hot-forges readily above 400 °C; do sheet/tube bending in O or T4 and age afterwards — T6 has limited bend radius and springback is high.
