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. best_for: 'Structural parts that must be strong but light: T6 and T651 plate with minimum proof stress 255 MPa and density 2.70 g/cm3' weakest_at: Strength in the weld zone, which the supplier says is lowered by welding, and pitting or intergranular attack in chloride solution (lab immersion test at 50 °C) identity: formula: 'Al-Mg-Si-Mn wrought alloy (AA6082, EN AW-6082 [AlSi1MgMn]).

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. sources: wikipedia-6082: title: 6082 aluminium alloy (Wikipedia) url: https://en.wikipedia.org/wiki/6082_aluminium_alloy year: 2026 kind: web license: CC BY-SA 4.0 (cited, not reproduced) aalco-6082-plate: title: 'Aalco datasheet: Aluminium Alloy, Commercial Alloy 6082 T6/T651 Plate' id: AA6082, HE30, DIN 3.2315, EN AW-6082, ISO Al Si1MgMn, A96082 (designation list) url: https://www.aalco.co.uk/datasheets/Aluminium-Alloy_6082-T6~T651_148.ashx kind: datasheet license: Stockist datasheet (cited, not reproduced) aalco-6082-extrusion: title: 'Aalco datasheet: Aluminium Alloy, Commercial Alloy 6082 T6 Extrusions' url: https://www.aalco.co.uk/datasheets/Aluminium-Alloy-6082-T6-Extrusions_338.ashx kind: datasheet license: Stockist datasheet (cited, not reproduced) azom-6082: title: 'AZoM: Aluminium Alloys - Aluminium 6082 Properties, Fabrication and Applications' url: https://www.azom.com/article.aspx?ArticleID=2813 kind: web license: AZoM web page (cited, not reproduced) yieh-6082-plate: title: 'Yieh Technical Data Sheet: 6082 aluminum alloy plate' url: https://aluminum.yieh.com/Upfiles/EDUp/files/6000%20Series/TDS/AA6082/TDS-YIEH-6082-Plate.pdf kind: datasheet license: Manufacturer datasheet (cited, not reproduced) gleich-en-aw-6082: title: 'Gleich Aluminium technical data sheet: AL rolled plates EN AW-6082 (dated 03.05.2024)' url: https://gleich.de/wp-content/uploads/2021/03/en_en_aw_6082.pdf kind: datasheet license: Manufacturer datasheet (cited, not reproduced) thyssenkrupp-6082-mds: title: 'thyssenkrupp Materials (UK) Material Data Sheet: Aluminium Alloy 6082 (07/2016)' url: https://d2zo35mdb530wx.cloudfront.net/_legacy/UCPthyssenkruppBAMXUK/assets.files/material-data-sheets/aluminium/6082.pdf kind: datasheet license: Supplier datasheet (cited, not reproduced) hydro-6xxx-sds: title: 'Hydro: Wrought Aluminum Products, 6xxx Series Alloys, Safety Data Sheet (version 2.0)' url: https://www.hydro.com/globalassets/01-products--services/extruded-profiles/americas/ena-resources/safety-data-sheets/8-668-6xxx-series.pdf id: CAS 7429-90-5 (aluminium) kind: datasheet license: Manufacturer safety data sheet (cited, not reproduced) ecs-2017-6082: title: Xhanari and Finsgar, Electrochemical Analysis of AA6082 Aluminium Alloy in Chloride Media, Int.

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.
