Why it exists
Aluminium alloy 6082 is a wrought Al-Mg-Si alloy with manganese, built for strength. The plate datasheets give a minimum 0.2 % proof stress of 255 MPa and tensile strength of 300 MPa for T6 and T651 plate of 6 to 12.5 mm, and the highest of the 6000 series alloys according to the Yieh and thyssenkrupp datasheets. Its density is 2.70 g/cm3. The thyssenkrupp datasheet lists trusses, cranes, bridges and highly stressed structures as uses. Temper is set by heat treatment: T6 is solution heat treated and artificially aged, and T651 is also stress relieved by stretching. The profile keeps the temper and product form on each value.

Why choose it, and why not
Good for
- Structural parts: T6 and T651 plate with 255 MPa minimum proof stress and 2.70 g/cm3 density.
- Machined plate parts: the Yieh and thyssenkrupp datasheets both name machining as the main plate use.
- Welded structures and shipbuilding: the Gleich datasheet lists them among the applications.
Watch out for
- Weld zone: strength is lowered, according to the thyssenkrupp datasheet.
- Chloride: pitting and intergranular attack in lab tests, with more pitting at 50 °C than at 25 °C.
- Machining dust and fine chips: combustible, according to the Hydro 6xxx SDS.
- No spacecraft, cryogenic, radiation or outgassing data for 6082 was found in an opened source.

Risks and side effects
Hazards to people, what happens when a cell overheats, and how the material is handled and stored.
For people
The sources give a hazard for dust and chips from machining, not for the solid alloy. The Hydro sheet is a family SDS, so its hazard lines are general to the 6xxx series.
- Solid alloy
- The Hydro 6xxx sheet says the massive product is physiologically inert, and its Section 2 classification is Not classified.
- Dust and chips
- Dust, chips and fine turnings from machining can ignite more easily, and the dust is combustible. Aluminium dust has a respirable exposure limit of 1 mg/m³ (ACGIH TWA).
If it fails
The failure routes are a weld-zone strength loss and chloride attack. These come from a datasheet and one laboratory study, not from field failures.
- Weld zone
- The thyssenkrupp datasheet says strength is lowered in the weld zone and recommends alloy 4043 filler wire.
- Chloride
- In a lab test in 5 wt% NaCl at 25 °C the corrosion rate was 0.865 mg/(m²·h), and the paper says pitting is more pronounced at 50 °C.
Handling and storage
- Machining
- Use chip breakers, and take care to minimise dust. The Hydro sheet says fine chips and dust are combustible.
- Incompatible materials
- Keep away from strong acids, strong bases and strong oxidisers. Corrosive substances in contact with the metal can give off flammable hydrogen.
Test details
The original wording and numbers from the sources, for readers who want them.
Failure risks
| Failure | Trigger and consequence |
|---|---|
| Strength loss in the weld zonemoderate severity | Fusion welding of 6082 without post-weld treatmentThe thyssenkrupp datasheet says 6082 has very good weldability but strength is lowered in the weld zone, and recommends alloy 4043 filler wire when welding to itself (5356 when welding to 7005). |
| Pitting and intergranular corrosion in chloride solutionsmoderate severity | Chloride exposure (NaCl at 25 and 50 °C in the lab test); the paper notes 6xxx alloys are susceptible to pitting and intergranular corrosionCorrosion rate rises with chloride concentration, and pitting is more pronounced at 50 °C. The paper gives no damage or life figures. |
Handling and storage
- Fine dust and chips from machining can ignite, and processing should be done with care to minimise dust. Keep the material away from water and moist air during processing, since the SDS says they should be avoided. Incompatible with strong acids, strong bases and strong oxidisers, and corrosive substances in contact with the metal can produce flammable hydrogen gas.
- Machining swarf in T6 and T651 breaks into tight coils when chip breakers are used, so chip breakers should be used.
Supply and geography
How common the raw materials are and where they come from.
Aluminium (primary smelter production)
- Top producers (2025)
- China 60.8%, India 5.7%, Russia 5.3%, Canada 4.5%, United Arab Emirates 3.6%
- Recycling
- USGS: in 2025 aluminium recovered from purchased scrap in the United States was about 3.6 million tons.
- Substitutes
- USGS: composites, magnesium, steel and titanium can substitute for aluminium in ground transportation uses.

summary: |
Aluminium alloy 6082 (EN AW-6082, AlSi1MgMn) is a wrought Al-Mg-Si alloy with manganese. In the T6 and T651 temper the plate datasheets give a minimum 0.2 % proof stress of 255 MPa and a tensile strength of 300 MPa for plate of 6 to 12.5 mm, with 9 % elongation on a 50 mm gauge. Its density is 2.70 g/cm3 and its thermal conductivity 180 W/(m·K) in one datasheet. Suppliers call it the highest-strength 6000-series alloy and a structural alloy that has replaced 6061 in many uses.

- environment: Chloride solution, 1 and 5 wt% NaCl at 25 and 50 °C (immersion and electrochemistry)
headline: Corrosion rate rises with chloride concentration, and pitting is more marked at 50 °C.
effect: At 25 °C the rate was 0.587 and 0.865 mg/(m²·h) in 1 and 5 wt% NaCl. At 50 °C the samples gained mass because corrosion products stayed on the surface. The paper says the rate rises with chloride concentration, that pitting is more pronounced at 50 °C, and that the highest temperature gives the highest corrosion rates.

hazards:
- text: Hydro's 6xxx-series SDS (family sheet, not 6082 alone) classifies the product as Not classified under GHS-US and Canada in Section 2. Section 3 lists aluminium (CAS 7429-90-5, more than 89.9 %) with Flam. Sol. 1, H228 and Water-react. 2, H261 for the element. It says the massive product is physiologically inert, but user-generated dust and fumes may pose a hazard.

consequence: The thyssenkrupp datasheet says 6082 has very good weldability but strength is lowered in the weld zone, and recommends alloy 4043 filler wire when welding to itself (5356 when welding to 7005).
severity: moderate
source: thyssenkrupp-6082-mds

- mode: Pitting and intergranular corrosion in chloride solutions
trigger: Chloride exposure (NaCl at 25 and 50 °C in the lab test); the paper notes 6xxx alloys are susceptible to pitting and intergranular corrosion
consequence: Corrosion rate rises with chloride concentration, and pitting is more pronounced at 50 °C. The paper gives no damage or life figures.

gaps:
- Spacecraft, rocket or satellite use of 6082 was not found. A search of NASA and ESA material found 6061 and 7075 named for CubeSat and smallsat primary structures, and no source names 6082 for space hardware. No space use is recorded.
- The Xometry 6082 datasheet returned HTTP 403 and was not read. The Hydro and Constellium 6082 datasheets were not found in search results.
- 'PubChem aluminium GHS record: blocked by a bot-check page, so the ECHA classification for the element was not read. The Hydro 6xxx SDS is a family sheet, not an SDS for 6082 alone.'
- 'Melting point differs between sources: 555 °C (Aalco and thyssenkrupp), 575 °C (Yieh) and 585 to 650 °C (Wikipedia infobox). All three are kept with notes, and none is reconciled.'
- 'Electrical resistivity: AZoM prints 0.38 x10-6 Ω.m against 0.038 in Aalco, Yieh and thyssenkrupp. The 0.038 value is used, and the AZoM figure is not.'
- 'Composition: the Yieh datasheet prints Mn 0.6 to 1.2 and Mg 0.8 to 1.2 wt%, against 0.4 to 1.0 and 0.6 to 1.2 in the EN 573-3 figures printed by Aalco, thyssenkrupp, AZoM and Wikipedia. The EN 573-3 figures are used.'
- 'Designations: AA6082 is printed in the lists (AA, not a system name in the designation list) and HE30 is printed, but no source names the standard for HE30, so it is not listed as a designation. A96082 is printed without a system label and is entered as UNS with a note. No trade name is printed.'
- Hardness, electrical conductivity and corrosion rate are not in the canonical property file. They use the snake_case names hardness_brinell, electrical_conductivity and corrosion_rate_immersion, and the immersion rates are lab values for one sample, not a product grade rating.
- Mechanical values for O and T4 tempers come from one BS EN table (AZoM) only, with maximum or minimum limits, and only the O-temper proof stress is entered. T4 values are not entered as properties.
- The corrosion rates are a single lab study on one sample composition. No atmospheric, seawater or space-exposure corrosion rate for 6082 was found in an openly readable source.
- Critical-mineral listing for aluminium was not found in the USGS 2026 aluminum summary as read, so critical_lists is empty.
- No radiation, cryogenic, outgassing, cold-welding or atomic-oxygen data for 6082 was found in an opened source.

story:
risk_groups:
- title: For people
lead: The sources give a hazard for dust and chips from machining, not for the solid alloy. The Hydro sheet is a family SDS, so its hazard lines are general to the 6xxx series.
points:
- label: Solid alloy
line: The Hydro 6xxx sheet says the massive product is physiologically inert, and its Section 2 classification is Not classified.
- label: Dust and chips
line: Dust, chips and fine turnings from machining can ignite more easily, and the dust is combustible. Aluminium dust has a respirable exposure limit of 1 mg/m³ (ACGIH TWA).
- title: If it fails
lead: The failure routes are a weld-zone strength loss and chloride attack. These come from a datasheet and one laboratory study, not from field failures.
points:
- label: Weld zone
line: The thyssenkrupp datasheet says strength is lowered in the weld zone and recommends alloy 4043 filler wire.
- label: Chloride
line: In a lab test in 5 wt% NaCl at 25 °C the corrosion rate was 0.865 mg/(m²·h), and the paper says pitting is more pronounced at 50 °C.
- title: Handling and storage
points:
- label: Machining
line: Use chip breakers, and take care to minimise dust. The Hydro sheet says fine chips and dust are combustible.
- label: Incompatible materials
line: Keep away from strong acids, strong bases and strong oxidisers. Corrosive substances in contact with the metal can give off flammable hydrogen.
why: 'Aluminium alloy 6082 is a wrought Al-Mg-Si alloy with manganese, built for strength. The plate datasheets give a minimum 0.2 % proof stress of 255 MPa and tensile strength of 300 MPa for T6 and T651 plate of 6 to 12.5 mm, and the highest of the 6000 series alloys according to the Yieh and thyssenkrupp datasheets. Its density is 2.70 g/cm3. The thyssenkrupp datasheet lists trusses, cranes, bridges and highly stressed structures as uses. Temper is set by heat treatment: T6 is solution heat treated and artificially aged, and T651 is also stress relieved by stretching. The profile keeps the temper and product form on each value.'
uses:
- where: Structures and transport
line: The thyssenkrupp datasheet lists milk churns, trusses, cranes, ore skips, beer barrels, bridges, highly stressed applications and transport applications. The Gleich datasheet lists welded constructions and shipbuilding.
- where: Machined parts
line: The Yieh datasheet says that in plate form 6082 is the alloy most commonly used for machining, and that T6 and T651 machine well and produce tight coils of swarf with chip breakers.
can_do:
- label: Strength, T6 plate
value: 255 MPa minimum proof stress
line: For T6 and T651 plate of 6 to 12.5 mm, the datasheets give a minimum proof stress of 255 MPa and a minimum tensile strength of 300 MPa, with 9 % elongation on A50 mm.
- label: Strength, T651 plate
value: 295 to 310 MPa tensile
line: For T651 plate of 20 to 80 mm the Gleich datasheet gives typical tensile strengths of 295 to 310 MPa and proof stress of 240 to 260 MPa.
- label: Weight
value: 2.70 g/cm3
benchmark: density
line: Density is 2.70 g/cm³ in the Aalco datasheet, and the Gleich plate datasheet prints the same figure.
- label: Heat
value: 170 to 220 W/(m·K)
benchmark: thermal_conductivity
line: The Gleich plate datasheet gives typical thermal conductivity of 170 to 220 W/(m·K) at room temperature, and the Aalco datasheet prints 180 W/(m·K).
- label: Service temperature
value: 120 °C long term
benchmark: max_service_temp
line: The Gleich datasheet gives a maximum use temperature of 120 °C for long-term use and 160 °C for short-term use, with no loss of strength after cooling down.
compare: In this profile the 6082 record is a structural alloy, and the datasheets rank it as the highest-strength 6000-series alloy and a replacement for 6061 in many uses. The sources give no strength-per-mass numbers against other alloys or against composites, so the profile does not rank it.
compare_rows:
- label: Density
benchmark: density
- label: Yield strength
benchmark: yield_strength
- label: Thermal conductivity
benchmark: thermal_conductivity
handling:
- Specify the temper and product form, since strength and conductivity differ between O, T4, T6 and T651.
- Use filler wire 4043 when welding 6082, and allow for the strength drop in the weld zone.
- Keep machining dust and fine chips away from ignition sources, and avoid contact with water.
good_for:
- 'Structural parts: T6 and T651 plate with 255 MPa minimum proof stress and 2.70 g/cm3 density.'
- 'Machined plate parts: the Yieh and thyssenkrupp datasheets both name machining as the main plate use.'
- 'Welded structures and shipbuilding: the Gleich datasheet lists them among the applications.'
watch_out:
- 'Weld zone: strength is lowered, according to the thyssenkrupp datasheet.'
- 'Chloride: pitting and intergranular attack in lab tests, with more pitting at 50 °C than at 25 °C.'
- 'Machining dust and fine chips: combustible, according to the Hydro 6xxx SDS.'
- No spacecraft, cryogenic, radiation or outgassing data for 6082 was found in an opened source.
verdict: Aluminium alloy 6082 is a strong, machinable Al-Mg-Si-Mn structural alloy. In T6 and T651 plate its datasheets give a minimum proof stress of 255 MPa and tensile strength of 300 MPa, with density 2.70 g/cm3. Its weak points are the strength loss in welds, pitting in chloride solution, and fire risk from fine machining dust. No spacecraft or cryogenic data for 6082 was found.
recipe:
line: 'Wrought Al-Mg-Si-Mn alloy. Composition limits in wt% from the EN 573-3 figures printed by Aalco and thyssenkrupp: silicon 0.7 to 1.3, magnesium 0.6 to 1.2, manganese 0.4 to 1.0, with iron, copper, zinc, titanium and chromium at their maxima and aluminium the balance. Heat treatment for T6 is solution treatment then artificial ageing, and for T651 solution treatment, stretching to relieve stress, then artificial ageing (thyssenkrupp datasheet).'
