summary: |
  AW-8079 (AlFe1Si) is a wrought aluminium alloy with 0.7 to 1.3 % iron and 0.05 to 0.3 % silicon. A supplier page prints its density as 2.72 g/cm3 in condition O foil. Another supplier page prints a tensile strength of 170 to 175 MPa and a yield strength of 155 MPa for H19 foil. One page describes the alloy as "Aluminum for food using". No corrosion test, space result or flight data for this alloy were found.
best_for: 'Food-contact foil and thin sheet, where the suppliers describe the alloy as food grade (Euralliage: ''Aluminum for food using'')'
weakest_at: 'Strength depends strongly on temper: 45 to 110 MPa in condition O against 170 to 175 MPa in H19 foil. No corrosion or space test data were found.'

gaps:
  - No elongation value for condition O or H19 foil was found. The only elongation row is a lower limit of 1 % from TotalMateria, with no temper printed.
  - Mfgrobots prints melting range, thermal conductivity, electrical conductivity and modulus as typical values for wrought 8000 series aluminium. These describe the family, not AW-8079, so they are left out.
  - Euralliage prints no mechanical or physical characteristic for this alloy and says it is produced in limited quantity for fields not covered by the European standard. This conflicts with the Mfgrobots and TotalMateria pages, which print values and cite EN 573-3, and the conflict is not resolved here.
  - The EN 573-3 or EN 546 standard text was not opened, so the composition limits are the printed ranges from supplier pages and not the standard itself.
  - No failure risk (hot strength, fatigue, pinholes, delamination) for alloy 8079 was found in the sources read.
  - No corrosion test for alloy 8079 was found. The corrosion entry only records a general statement about aluminium's oxide layer.
  - Crustal abundance of aluminium was not looked up in a readable source for this profile.
  - No space, vacuum, outgassing, radiation or flight result for alloy 8079 was found.
  - The PubChem hazard codes are for aluminium powder. No hazard classification for 8079 foil was found.
  - Only one food-contact use and one heat-exchanger use were found. No space application source was found, and the food-packaging use is filed under the nearest tag in the site list.
  - TotalMateria lists 15 of 52 cross-references (including AFNOR, BDS, CSN and MSZ entries). These were not opened, so no national designation is recorded other than those listed in identity.
  - The USGS 2025 critical-minerals list was read through its web page. The page text could not be extracted for a raw check, so the list entry rests on that page summary.

  note: Read by an AI assistant on 2026-11-01 from the supplier, materials-data and USGS pages named above. Composition ranges, tensile and yield values are from supplier pages that do not name an EN 573-3 table or a temper for every row. The O-condition tensile range is an envelope of twelve printed ranges. Euralliage prints no mechanical values for this alloy.
story:
  recipe:
    line: AW-8079 (AlFe1Si) is a wrought aluminium alloy. It is mostly aluminium, with iron and silicon as the main additions, and copper and zinc as small minor elements. The composition figures are nominal values printed on the supplier pages, not measured values.
    parts:
      - name: Aluminium
        symbol: Al
        share: the balance of the alloy
        role: The base metal. It sets the density and the conductivity of the alloy.
      - name: Iron
        symbol: Fe
        share: 0.7 to 1.3 %
        role: The main addition. It gives the alloy its strength in the annealed and cold-worked tempers.
      - name: Silicon
        symbol: Si
        share: 0.05 to 0.3 %
        role: A minor addition that works with iron to form the AlFe1Si composition.
      - name: Copper
        symbol: Cu
        share: 0.05 %
        role: A trace element, printed as a single value.
      - name: Zinc
        symbol: Zn
        share: 0.1 %
        role: A trace element, printed as a single value.

      verdict: Powder is flammable; foil not classified
      lead: The hazard codes found are for aluminium powder. No hazard classification for the rolled alloy was found.
      points:
        - label: Powder
          line: PubChem lists H250 (catches fire spontaneously if exposed to air) for uncoated aluminium powder and H228 (flammable solid) for coated powder.
        - label: Foil
          line: The sources read give no hazard classification for AW-8079 foil.
    - title: Food contact
      level: 1
      verdict: Described as food grade by suppliers
      lead: Suppliers describe the alloy as food grade, but the sources do not include a food-contact test.
      points:
        - label: Supplier wording
          line: Euralliage describes the alloy as 'Aluminum for food using'. Mfgrobots calls it food safe.
        - label: Limits
          line: No migration or food-contact test result was found for this alloy.
    - title: Handling and storage
      points:
        - label: Storage
          line: No storage or handling rule for alloy 8079 was found in the sources read.
  why: AW-8079 (AlFe1Si) is a wrought aluminium alloy with iron and silicon as its main additions, at 0.7 to 1.3 % iron and 0.05 to 0.3 % silicon. Suppliers offer it mainly as foil and thin sheet, and describe it as food grade. Its strength depends strongly on temper. Condition O is printed with tensile ranges that together run from 45 to 110 MPa, and H19 foil is printed at 170 to 175 MPa tensile with a yield strength of 155 MPa. The profile records those printed numbers as supplier data.
  uses:
    - where: Thin sheet for heat exchangers
      line: Euralliage lists thin sheets, including thin sheets for heat exchangers, among the shapes made from this alloy.
    - where: Food-contact and pharmaceutical foil
      line: Stanford Advanced Materials lists packaging foil in tempers O, H22 and H24, and pharmaceutical foil in H14 and H18. This is a terrestrial use, not a space application.
  can_do:
    - label: Density
      benchmark: density
      value: 2.72 g/cm3
      line: The density of condition O foil is 2.72 g/cm3 as printed by Mfgrobots. TotalMateria prints 2.6 to 2.9 kg/dm3 for the grade.
    - label: Strength in H19 foil
      benchmark: ultimate_tensile_strength
      value: 170 to 175 MPa
      line: H19 foil is printed with a tensile strength of 170 to 175 MPa and a yield strength of 155 MPa (labelled RP02).
    - label: Strength in condition O
      benchmark: ultimate_tensile_strength
      value: 45 to 110 MPa
      line: In condition O the twelve printed tensile ranges run from 45 to 110 MPa at 20 °C. The page does not say which range fits a given product.
    - label: Stiffness
      benchmark: elastic_modulus
      value: 69 to 79 GPa
      line: TotalMateria prints a modulus of elasticity of 69 to 79 GPa for the grade over 0 to 30 °C, with the temper not stated.
  compare: 'Within this profile set, AW-8079 is an iron-silicon foil alloy rather than a structural alloy. Its strength depends strongly on temper: condition O is printed at 45 to 110 MPa tensile, and H19 foil at 170 to 175 MPa. The sources do not agree on whether the alloy has a full standard. Mfgrobots and TotalMateria cite EN 573-3 and print values, while Euralliage says no mechanical or physical characteristic is specified for it. No like-for-like comparison with other aluminium grades was possible from these sources.'

    - label: Yield strength
      benchmark: yield_strength
  handling:
    - No storage or handling rule for alloy 8079 was found in the sources read.
    - State the temper when ordering, because the printed strength ranges differ between condition O and H19 foil.
    - The Euralliage page calls the alloy food grade; no food-contact test result was found.
  good_for:
    - 'Food-contact foil: suppliers describe the alloy as food grade.'
    - Thin sheet for heat exchangers, per the Euralliage shapes list.
  watch_out:
    - Strength varies strongly with temper, from 45 to 110 MPa in condition O to 170 to 175 MPa in H19 foil.
    - No corrosion, space or flight test was found for this alloy.
    - The sources disagree on whether a full EN standard covers the alloy.
  verdict: AW-8079 is an iron-silicon aluminium alloy sold mainly as food-contact foil and thin sheet. Suppliers print a density of 2.72 g/cm3 and temper-dependent strengths. The sources contain no corrosion, space or flight data for the alloy.
