summary: |
  Aluminium alloy 5754 (EN AW-5754, AlMg3) is a wrought aluminium-magnesium alloy with 2.6 to 3.6 % magnesium. Datasheets describe it as having excellent resistance to seawater and industrial chemical attack, and it is easy to weld. Its density is 2.66 to 2.67 g/cm3. Strength depends on the temper: the tensile range is 190 to 260 MPa in H114 sheet, 240 to 280 MPa in H24 sheet and plate, and 245 to 290 MPa in H22.
best_for: Welded structures and marine or chemical service where seawater corrosion resistance matters, at a density of about 2.67 g/cm3
weakest_at: Strength against heat-treatable aluminium alloys, since strength comes from the temper, and the risk of sensitisation in magnesium-rich grades held warm for long periods (no temperature threshold for this grade was verified)
identity:
  formula: Aluminium with 2.6 to 3.6 wt% magnesium, 0.1 to 0.6 wt% manganese plus chromium, and limits of 0.4 wt% iron, 0.4 wt% silicon, 0.1 wt% copper, 0.2 wt% zinc and 0.15 wt% titanium (EN AW-AlMg3, composition limits as printed for EN 573-3)

corrosion:
  - environment: Seawater and industrially polluted atmospheres
    headline: 5754 is marketed for excellent resistance to seawater and polluted air; no measured corrosion rate was found for this grade.
    effect: The Smiths datasheet says the alloy is highly resistant to both seawater and industrial chemical attack. The Righton H114 datasheet says it has excellent resistance to seawater and industrial chemical corrosion. Neither gives a corrosion rate, pit depth or exposure time.

    headline: Magnesium-rich 5XXX alloys are checked for sensitisation, which makes them prone to intergranular attack. The temperature and time that matter for 5754 were not found in a page we could open.
    effect: A Virginia MS thesis on marine-grade 5XXX aluminium-magnesium alloys studies electrochemical etchants used to detect sensitisation. The abstract read gives no magnesium content or temperature in degrees Celsius.

  failure_risks:
    - mode: Sensitisation of magnesium-rich grain boundaries
      trigger: Long exposure of a magnesium-rich 5XXX alloy to warm service (no temperature or time threshold verified for 5754)
      consequence: Sensitised grain boundaries are vulnerable to intergranular corrosion. The thesis is a study of how to detect this condition; no rate or threshold was read.
      severity: moderate

      where: Title and abstract
    - mode: Lower ductility in strain-hardened tempers
      trigger: Choosing H24 instead of H114 for formed parts
      consequence: Minimum A50 elongation falls from 12 % in H114 (0.2 to 6.00 mm) to 6 % in H24 (0.2 to 25 mm), so the harder temper has less ductility for forming.

  - No space, vacuum, outgassing, atomic-oxygen, radiation or cryogenic result for 5754 was found in a page we could open. No NASA source was located, so no tags.environments or tags.stresses are set.
  - The PubChem aluminium hazard record was blocked by an access check. The GHS wording comes from the Metals Depot SDS, which covers aluminium alloys in general and does not name 5754.
  - No magnesium content or temperature threshold for sensitisation in 5754 was found. The Buczynski thesis abstract read gives no numbers, and the Springer and Nature pages (srep26870) and the MDPI Coatings page were blocked.
  - No corrosion rate, pitting depth, atmospheric rate or seawater exposure data for 5754 found in a page we could open.
  - Production route (casting, homogenising, hot and cold rolling, annealing) not described from a fetched source; the story gives composition only.
  - Strength values cover H114, H24 and H22 only, from distributor and supplier datasheets. H111, O and H32 values were not read, and the Abrams and Weerg rows carry no temper, so they are kept as not stated.
  - The Smiths datasheet gives magnesium as 2.60 to 3.20 %, which conflicts with 2.6 to 3.6 % printed by Abrams and Righton (BS EN 573-3). The file uses the Abrams and Righton range and does not use the Smiths limit.
  - 'Righton lists A95754 as a corresponding designation but says it ''may not be a direct equivalent''. The UNS entry uses the Smiths related-specifications list instead. Trade names: none found in a fetched page.'
  - Electrical conductivity is not a canonical property name in property-canon.yaml, so it is used as printed in m/(Ω·mm²). Hardness is recorded as hardness_brinell, also not in property-canon.yaml.
  - Photos and drawings (media) not added. Atomic weights not given because the composition is set as weight-percent limits, not a formula.

review:
  status: draft
  method: assistant
  checked_values: 24
  unreachable: 4
  caveats: 5
  note: 'Values were read by an AI assistant on 2026-10-25 from the datasheets and the USGS text named in each entry. Unreachable: Aalco H26 datasheet, PubChem aluminium record, Springer and Nature (srep26870) and MDPI Coatings page. Caveats: tensile and proof values are distributor or supplier minimums and ranges for one temper each; the Smiths magnesium limit conflicts with BS EN 573-3; the supply shares are calculated from USGS 2025e smelter production; the hazard wording is from a generic aluminium-alloy SDS; the sensitisation entry rests on a thesis title and abstract without numbers.'
story:
  risk_groups:
    - title: For people
      lead: The solid alloy is not classified as hazardous. The hazards come from cutting, grinding, melting and welding, which give off dust and fumes.
      level: 1
      verdict: Low hazard as solid metal
      points:
        - label: Solid alloy
          line: The Metals Depot safety data sheet for aluminium alloys in the 1000 to 7000 series calls the solid metal an article, not hazardous in solid form. It does not name 5754.
        - label: Processing
          line: Dust from grinding can burn if ignited, and fumes at melting or welding contain aluminium oxides. Ventilation and dust control are the main precautions.
    - title: If it fails
      lead: The failure routes in the sources are sensitisation in warm service and lower ductility in harder tempers.
      points:
        - label: Sensitisation
          line: A thesis on marine-grade 5XXX alloys studies how to detect sensitisation, the grain-boundary condition that makes these alloys prone to intergranular attack. The abstract read gives no temperature for 5754.
        - label: Temper choice
          line: The H24 datasheet gives a minimum A50 elongation of 6 %, against 12 % for H114, so the harder temper forms less.
    - title: Handling and storage
      points:
        - label: Dust and fumes
          line: Avoid generating dust and breathing metal fumes. Keep the work area ventilated.
        - label: Welding
          line: Smiths rates the alloy as excellent in weldability and poor in brazability.
  why: 'Alloy 5754 is an aluminium-magnesium alloy with 2.6 to 3.6 % magnesium. Datasheets describe excellent resistance to seawater and industrial chemical attack, and easy welding. Its density is 2.66 to 2.67 g/cm3. Strength depends on the temper: the datasheets give tensile strengths of 190 to 260 MPa in H114 sheet, 240 to 280 MPa in H24 sheet and plate, and 245 to 290 MPa in H22.'
  uses:
    - where: Vehicle bodies and ships
      line: Datasheets list shipbuilding, vehicle bodies, fishing equipment and food processing among the uses of 5754. Abrams also lists container and architectural construction.
    - where: Welded chemical and nuclear structures
      line: Smiths lists welded chemical and nuclear structures among the applications, and says the alloy is used in marine, oil and gas, chemical and nuclear sectors. No space-flight use was found in the sources read.
  can_do:
    - label: Weight
      value: 2.67 g/cm3
      benchmark: density
      line: Density is 2.67 g/cm3 in Abrams and 2.66 g/cm3 for H22 in Smiths.
    - label: Strength by temper
      value: 190 to 260 MPa (H114)
      benchmark: ultimate_tensile_strength
      line: Tensile strength is 190 to 260 MPa in H114 sheet (0.2 to 6.00 mm), 240 to 280 MPa in H24 sheet and plate, and 245 to 290 MPa in H22.
    - label: Heat conduction
      value: 140 to 160 W/(m·K)
      benchmark: thermal_conductivity
      line: Abrams gives 140 to 160 W/(m·K) at ambient temperature. Smiths gives 147 W/(m·K) for H22, and Weerg gives 132 W/(m·K) at 20 °C.
    - label: Melting
      value: 590 to 645 °C
      benchmark: melting_point
      line: Weerg gives a melting range of 590 to 645 °C, and Smiths gives 600 °C.
    - label: Joining
      value: Excellent weldability
      line: Smiths rates weldability as excellent and brazability as poor.
  compare: 'This file does not set 5754 against other profiles, because the numbers of those profiles were not read in this run. Read the compare rows against a reference point of your choice: the density is 2.66 to 2.67 g/cm3, the thermal conductivity is 132 to 160 W/(m·K), and the H114 tensile range is 190 to 260 MPa.'
  compare_rows:
    - label: Density
      benchmark: density
    - label: Thermal conductivity
      benchmark: thermal_conductivity
    - label: Tensile strength
      benchmark: ultimate_tensile_strength
  handling:
    - Specify the temper, because strength runs from 190 to 290 MPa across H114, H24 and H22, and elongation falls in harder tempers.
    - Keep dust down when cutting, grinding or welding, and ventilate the work area.
    - Do not pour water onto molten metal, since the SDS says it may be explosive.
  good_for:
    - 'Seawater and polluted-air service: the datasheets describe excellent resistance to seawater and industrial chemical attack.'
    - 'Welded fabrication: excellent weldability, per Smiths.'
    - 'Light structures: density of 2.66 to 2.67 g/cm3.'
  watch_out:
    - Sensitisation in magnesium-rich grades held warm for long periods. No temperature threshold for 5754 was verified.
    - Harder tempers such as H24 give 6 % minimum elongation, against 12 % for H114.
    - No corrosion rate, space test or outgassing result for this grade was found.
  verdict: Alloy 5754 is a weldable, seawater-resistant aluminium-magnesium sheet alloy with a density of about 2.67 g/cm3. Its strength depends on the temper, and this profile has no measured corrosion rate, space test or sensitisation threshold for the grade.
  recipe:
    line: 'Aluminium alloy 5754 is an aluminium-magnesium alloy.
