summary: |
  Aluminium alloy 8011 (UNS A98011) is a wrought Al-Fe-Si alloy of about 98.7 % aluminium with 0.5 to 0.9 % silicon and 0.6 to 1.0 % iron in the foil specification. It is sold as foil for packaging, container and blister uses, and it is used for heat-exchanger fins. A reseller sheet for the European equivalent EN AW-8011A gives 2.71 g/cm3 density, 70 GPa modulus, 180 to 195 MPa tensile strength and 210 to 220 W/(m·K) thermal conductivity for H19 foil at 20 °C. No yield strength and no space flight data were found in the sources read.

gaps:
  - Yield strength of AA8011 foil in any temper was not found. MakeItFrom returned 403 Forbidden, a Croatian paper page was a waiting page, and the supplier listings print no yield value that could be read.
  - No tensile or elongation value for H18, H22, H24 or O foil was read in a fetched page. The one tensile range is for H19 from a property sheet for EN AW-8011A.
  - The H19 values come from a sheet for EN AW-8011A (citing EN 573-3), not from a mill datasheet for AA 8011 foil. yieh.com prints EN AW-8011A as the European name for 8011, but the equivalence should be confirmed against EN 573-3.
  - 'Corrosion: no numeric corrosion rate, potential or current for AA8011 was read. The 2021 friction-stir-weld study gives only the qualitative abstract statement. The 2014 acid-electrolyte study was seen only as a search snippet, and the full Amrita paper was not opened.'
  - Spacecraft, rocket or satellite use of AA8011 was not found in any source read. Searches on multilayer insulation and thermal straps named alloys 1145 and 1235 but not 8011, so the uses list has no space use.
  - Only two uses entries fit the application list (both thermal-control, heat-exchanger fins). The packaging, container and pharmaceutical blister foil uses (samaterials, yieh) have no matching application value in the schema, so they are recorded in story.uses only.
  - PubChem's aluminium GHS record was blocked by a reCAPTCHA page. The hazard entries rest on the Alcoa SDS for the sheet, coil and foil family, which lists 8011 among its synonyms. Its composition ranges cover the whole family and are not used as 8011 values.
  - The USGS 2026 aluminum summary read in this run does not mention a critical-minerals list, so no critical-list entry is recorded.
  - The W.Nr. 3.0280 number and the aluminium atomic weight were not printed on any page read in this run, so they are left out.
  - The production route (smelting, casting and rolling to foil) is not described from a fetched source. The only process facts are a laboratory study that homogenised a sample at 600 °C for 24 h and quenched it in water (Gonzalez et al. 2006).
  - Precipitation temperatures from the DSC study (271.8, 450 and 474.2 °C) were not entered, because the heating conditions are only partly readable in the extracted text.
  - The mfgrobots page gives specific heat, Poisson ratio and fracture toughness only as typical values for the wrought 8000 series, not for 8011, so they are left out.
  - Hardness of at least 25 HB on totalmateria has no temper, and the page has no canonical hardness name, so it is not entered.

  note: 'Values were read by an AI assistant on 2026-10-26 from the pages named in each entry. H19 values come from a sheet for EN AW-8011A, not from a datasheet for AA 8011 foil. Unreachable: MakeItFrom (403), PubChem (reCAPTCHA), CroRIS waiting page for a Croatian foil paper. Caveats: no yield strength; totalmateria ranges have no temper; no corrosion number; no space use; hazards from a multi-alloy SDS.'
story:
  risk_groups:
    - title: For people
      lead: As supplied, the foil and sheet are not classified as hazardous. The hazard in use is dust and fine chips from processing.
      level: 1
      verdict: Low as supplied
      points:
        - label: The foil
          line: The Alcoa safety data sheet for sheet, coil and foil (a family sheet that lists 8011 among its synonyms) says the product is an article that should not pose a health hazard, and it is not classified under physical, health or environmental criteria.
        - label: Dust and fumes
          line: Dust and fumes from processing can irritate the eyes, skin and upper airways. The sheet lists asthma, chronic lung disease and skin rashes as conditions that dust can make worse.
    - title: If it fails
      lead: The failure routes in the sources are dust explosion and thermite reactions with metal oxides. No corrosion rate was found.
      points:
        - label: Dust explosion
          line: The sheet says even a minor dust cloud can explode violently, and chips and fines in contact with water give off hydrogen gas.
        - label: Thermite
          line: Molten aluminium reacts violently with iron oxide (rust), and with copper and lead oxides, so fines must be kept apart from rust and other metal oxides.
    - title: Handling and storage
      points:
        - label: Keep it dry
          line: Keep the material dry, avoid generating dust, and avoid contact with sharp edges or heated metal.
        - label: Temper
          line: The H19 figures do not apply to annealed O foil. The published tempers for 8011 foil run from O to H28 (yieh.com).
  why: Aluminium alloy 8011 is an Al-Fe-Si alloy, with iron and silicon as its main alloying additions (Gonzalez et al. 2006; Wikipedia 8000 table). In the H19 condition, one reseller sheet for the European name EN AW-8011A gives a tensile strength of 180 to 195 MPa, a density of 2.71 g/cm3 and a thermal conductivity of 210 to 220 W/(m·K) at 20 °C. A 2021 abstract names heat-exchanger fins as a typical use. The published foil specifications cover packaging, container and blister foil in several tempers.
  uses:
    - where: Heat-exchanger fins
      line: A 2021 abstract says AA8011 is typically used in air-conditioning ducts and heat-exchanger fins in ships and boats. This is marine service, not a spacecraft use.
    - where: HVAC and refrigeration fin stock
      line: A LODEC Group finstock page lists 8011 finstock in O and H tempers as available for HVAC, refrigeration and other heat-exchanger applications. This is building and refrigeration equipment, not a spacecraft use.
    - where: Packaging and blister foil
      line: Stanford Advanced Materials lists 8011 foil for packaging in the thin gauges of its foil table, container foil and pharmaceutical blister foil, with tempers including O, H14, H18, H22 and H24.
  can_do:
    - label: Carry heat
      value: 210 to 220 W/(m·K)
      benchmark: thermal_conductivity
      line: Thermal conductivity of H19 foil at 20 °C is 210 to 220 W/(m·K). A materials database gives the same range without a temper.
    - label: Light weight
      value: 2.71 g/cm3
      benchmark: density
      line: Density of H19 foil is 2.71 g/cm3 at 20 °C.
    - label: Strength in H19
      value: 180 to 195 MPa
      benchmark: ultimate_tensile_strength
      line: Tensile strength of H19 foil at 20 °C is printed as 180.0 and 195.0 MPa. No yield strength for this temper was found.
    - label: Stiffness
      value: 70.0 GPa
      benchmark: elastic_modulus
      line: The modulus of elasticity of H19 is 70.0 GPa at 20 °C.
    - label: Melting range
      value: 640 to 655 °C
      benchmark: melting_point
      line: The melting range of H19 is printed as 640.0 to 655.0 °C.
  compare: The USGS says copper can replace aluminium in electrical and heat-exchange applications, and that composites, steel and titanium can substitute in ground transport. The 8011 values here are from one reseller sheet for EN AW-8011A and a materials database that does not name a temper, so compare them with the other alloy profiles on this site only after checking each one's temper.
  compare_rows:
    - label: Density
      benchmark: density
    - label: Thermal conductivity
      benchmark: thermal_conductivity
    - label: Thermal expansion
      benchmark: cte
  handling:
    - Specify the temper, because the H19 values do not apply to annealed O foil.
    - Keep dust and fines dry and apart from rust and other metal oxides, to avoid dust explosions and thermite reactions.
    - Avoid contact with sharp edges and heated metal, as the SDS advises.
  good_for:
    - 'Light heat-exchanger fins: 2.71 g/cm3 density and 210 to 220 W/(m·K) conductivity in H19 foil at 20 °C.'
    - Packaging, container and blister foil in tempers from O to H28, per the published foil specifications.
  watch_out:
    - No yield strength is recorded for any temper, so the strength figures alone do not show how the foil will deform.
    - The H19 values come from a sheet for EN AW-8011A, not from an AA 8011 datasheet.
    - No corrosion rate, no spacecraft use and no outgassing data were found for this alloy.
  verdict: Aluminium alloy 8011 is a light, conductive foil and fin alloy. H19 foil shows 180 to 195 MPa tensile strength, 2.71 g/cm3 density and 210 to 220 W/(m·K) conductivity at 20 °C, but this profile has no yield strength, no corrosion number and no space flight use.
  recipe:
    line: 'AA 8011 is a wrought Al-Fe-Si alloy: the Wikipedia 8000-series table gives 98.7 % Al, 0.7 % Fe and 0.6 % Si, and foil specifications set iron at 0.60 to 1.00 % and silicon at 0.50 to 0.90 % (yieh.com; Stanford Advanced Materials). A laboratory study measured the Fe and Si in one sample, which was homogenised it at 600 °C for 24 h and quenching it in water (Gonzalez et al. 2006). The production route to foil is not described from a fetched source.'
    parts:
      - name: Aluminium
        symbol: Al
        share: 98.7 wt % (Wikipedia 8000 table); remainder of the specification
        role: The matrix. Almost all of the alloy is aluminium, which gives the foil its light weight and conductivity.
      - name: Iron
        symbol: Fe
        share: 0.7 wt % (Wikipedia 8000 table); 0.60 to 1.00 % (foil specification)
        role: Main alloying element together with silicon. The 2006 study found Al-Fe-Si phases in its AA8011 sample.
      - name: Silicon
        symbol: Si
        share: 0.6 wt % (Wikipedia 8000 table); 0.50 to 0.90 % (foil specification)
        role: Main alloying element together with iron (Gonzalez et al. 2006 describes the alloy as made mainly of Fe and Si).
