Aluminum 6182
AA 6182 · UNS A96182 · EN AlSi1MgZr
6182 (A96182, AlSi1MgZr) is a zirconium-bearing Al-Si-Mg extrusion alloy in which Zr controls recrystallisation to keep the grain structure fine, improving extrudability and surface finish on complex sections.

Solution heat treated and naturally aged | Choose when profiles must be bent, stretch-formed or hemmed after heat treatment, with later T6 ageing if needed. | 130 | 235 | 19 | 66 HB | 39 % IACS |
Cooled from hot working and artificially aged | Economical press-quench temper for thin-wall architectural and decorative profiles where full T6 strength is not required. | 235 | 280 | 11 | 85 HB | 43 % IACS |
Solution heat treated and overaged (stabilized) | Overaged for dimensional stability and improved resistance to intergranular attack at the cost of ~10–15 % strength. | 250 | 290 | 13 | 85 HB | 46 % IACS |

What is 6182?
6182 (A96182, AlSi1MgZr) is a zirconium-bearing Al-Si-Mg extrusion alloy in which Zr controls recrystallisation to keep the grain structure fine, improving extrudability and surface finish on complex sections. Typical T6 properties are 290 MPa yield, 330 MPa tensile, 10% elongation, 98 HB (60 HRB) and a 69.5 GPa modulus, with 42% IACS conductivity and 170 W/m·K. It welds well but softens in the HAZ, is limited to about 150 °C in service and has only moderate formability once aged. 6082 is the nearest widely stocked alternative. 6182 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). 6182 has a yield strength of 290 MPa (42.1 ksi) and a tensile strength of 330 MPa (47.9 ksi) — stronger than 74% of aluminum grades. Elongation at break is 10% and the elastic modulus is 69.5 GPa (10.1 Msi).

Working with 6182
Is 6182 easy to machine?
Machines freely in T5/T6 with sharp polished-flute carbide tools, high speed and generous coolant/lubricant; gummy chips and built-up edge in O/T4.
Can 6182 be welded?
Readily GMAW/GTAW/FSW welded with 4043 (crack-resistant) or 5356 (strength/anodising match); expect HAZ softening to roughly T4 level unless post-weld aged.
Can 6182 be formed, bent or molded?
Extrudes well thanks to Zr-stabilised structure; bend and form in O or freshly quenched T4 (within a few hours of quench), then age to T6.

6182 — frequently asked
What is 6182 used for?
6182 is typically used for complex multi-void extruded sections, architectural profiles and curtain wall members, anodized trim and cover profiles, thin-wall hollow structural sections, extruded heat sinks and frame and rail profiles for equipment. In short: zr-refined extrusion alloy; complex thin-wall profiles; uniform anodizing tone.
What is the yield strength of 6182?
6182 has a typical yield strength of 290 MPa (42.1 ksi) and a tensile strength of 330 MPa (47.9 ksi) — stronger than 74% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is 6182 easy to machine?
Reasonably — machinability is rated good (58/100, worse than 54% of aluminum grades). Machines freely in T5/T6 with sharp polished-flute carbide tools, high speed and generous coolant/lubricant; gummy chips and built-up edge in O/T4.
Can 6182 be welded?
Yes — weldability is rated very good (72/100). Readily GMAW/GTAW/FSW welded with 4043 (crack-resistant) or 5356 (strength/anodising match); expect HAZ softening to roughly T4 level unless post-weld aged.
What surface finishes work on 6182?
Excellent clear, colour and hard anodising with uniform tone; also accepts chromate/Ti-Zr conversion coatings, powder coat and mechanical polishing.

Extrudes well thanks to Zr-stabilised structure; bend and form in O or freshly quenched T4 (within a few hours of quench), then age to T6.
What is the maximum service temperature of 6182?
6182 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 6182-T6 and 6182-O?
T6 is the default condition — standard peak-strength condition for structural extrusions and machined parts; the normally stocked temper. O: softest condition for maximum forming/bending before heat treatment. Yield strength is 290 MPa in T6 versus 60 MPa in O.
How much does 6182 cost?
6182 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.
