What is 6110A?
6110A (EN AW-6110A, AlMg0.9Si0.9MnCu) is a copper- and manganese-modified Al-Mg-Si extrusion alloy developed for the upper strength range of the 6000-series family. In T6 it reaches 355 MPa yield, 385 MPa tensile, 11% elongation and 115 HB (68 HRB), which suits load-bearing transportation and structural extrusions where 6082 is not strong enough. The copper addition reduces corrosion resistance and weldability relative to Cu-free 6000-series grades, conductivity is 40% IACS and service is limited to about 150 °C. 6082-T6 is the usual alternative where welding or chloride exposure dominates. 6110A has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 585°C (1,085 °F). 6110A has a yield strength of 355 MPa (51.5 ksi) and a tensile strength of 385 MPa (55.8 ksi) — stronger than 84% of aluminum grades. Elongation at break is 11% and the elastic modulus is 70 GPa (10.2 Msi).

Working with 6110A
Is 6110A easy to machine?
Machines well in T5/T6 with polished carbide tools, high speed and copious coolant; T4/O tempers are gummy and prone to built-up edge.
Can 6110A be welded?
MIG/TIG weldable with 4043 (or 5356 for anodizing colour match); expect 40–50% HAZ strength loss and hot-crack risk from the Cu — post-weld T6 ageing restores much of the strength.
Can 6110A be formed, bent or molded?
Extrudes at moderate press speed (harder than 6063/6082); bend and hydroform in T4/W temper then artificially age — cold bending in T6 needs generous radii (≥3t).

What surface finishes work on 6110A?
Takes clear and hard anodising well but Cu/Mn intermetallics give a slightly darker, less uniform tint; chromate-free conversion coating or powder paint is preferred where chloride exposure occurs.

6110A — frequently asked
What is 6110A used for?
6110A is typically used for high-strength structural extrusions, automotive bumper beams, vehicle seat and slide rails, chassis and subframe sections, crash management components and load-bearing transport profiles. In short: highest-strength 6000-series extrusion; cu-bearing, lower corrosion resistance; stronger than 6082-T6.
What is the yield strength of 6110A?
6110A has a typical yield strength of 355 MPa (51.5 ksi) and a tensile strength of 385 MPa (55.8 ksi) — stronger than 84% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is 6110A easy to machine?
Reasonably — machinability is rated good (60/100, worse than 51% of aluminum grades). Machines well in T5/T6 with polished carbide tools, high speed and copious coolant; T4/O tempers are gummy and prone to built-up edge.
Can 6110A be welded?
Yes — weldability is rated good (65/100). MIG/TIG weldable with 4043 (or 5356 for anodizing colour match); expect 40–50% HAZ strength loss and hot-crack risk from the Cu — post-weld T6 ageing restores much of the strength.

Extrudes at moderate press speed (harder than 6063/6082); bend and hydroform in T4/W temper then artificially age — cold bending in T6 needs generous radii (≥3t).
What is the maximum service temperature of 6110A?
6110A 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 6110A-T6 and 6110A-O?
T6 is the default condition — default stocked condition: maximum strength for crash-management and load-bearing extrusions. O: softest condition for heavy cold forming or deep bending before re-heat-treatment. Yield strength is 355 MPa in T6 versus 65 MPa in O.
How much does 6110A cost?
6110A is a premium-cost aluminum ($$$), cheaper than about 51% 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.
