summary: |
  5019 (AlMg5, also written EN AW-5019, UNS A95019, AA 5019) is a wrought aluminium-magnesium alloy with about 4.5 to 5.6 % magnesium as its main alloying element. Supplier data give a density of 2.64 g/cm3, a melting range of 575 to 630 °C, and a tensile strength of 270 to 350 MPa in the H12 form and 300 to 380 MPa in the H24 form. The supplier rates its seawater and weathering resistance as very good and says the alloy is food safe. The sources read for this profile give no yield strength and no spacecraft or flight record.
best_for: Wrought rod, tube and wire where seawater and weathering resistance matter (supplier rates both very good)
weakest_at: 'Thin data: no yield strength was found for any tested temper, and the supplier rates hard brazing as poor'

gaps:
  - No yield strength (Rp0.2) was recorded for 5019 in any temper. Total Materia prints it only behind a registration wall, the Mfgrobots pages give tensile values only, and the MakeItFrom and Wieland datasheet pages could not be read (HTTP 403 and 404).
  - No thermal expansion (CTE) value is recorded. The Mfgrobots H12 page prints four values with no clear condition, and the Total Materia CTE row is behind a registration wall.
  - Elongation for the Mfgrobots H12 listing is printed as 6, 7 and 8 % against A50 and A100 without a clear mapping, so it was left out. The Total Materia minimum (2 %, A) is recorded instead.
  - No application or use is confirmed for 5019 in any source read here. The H24 supplier page says the alloy is food safe, but it names no device or application, so the uses list is empty.
  - No flight, spacecraft, satellite or launch-vehicle record for 5019 was found.
  - No corrosion test data (salt spray, ASTM G66 or G67, exfoliation, stress corrosion) for 5019 was found. Only the supplier rating very good for seawater and weathering is recorded.
  - The hazard classes come from the Hydro SDS for the whole 5xxx product family, not a 5019-specific SDS. PubChem and an alloy-specific safety sheet were not read for this grade.
  - 'Designation conflict: the Bikar page prints DIN 3.3355, and Total Materia prints DIN 3.3555. Only 3.3555 is recorded, from Total Materia, and the Bikar figure is not entered.'
  - The magnesium range (4.5 to 5.6 %) comes from one supplier listing (Bikar), and the Total Materia magnesium row is behind a registration wall. Mn, Si, Fe, Cu, Cr, Zn and Ti limits are from the same Bikar listing only.
  - Electrical conductivity is recorded as electrical resistivity from Total Materia, so the Mfgrobots conductivity of 15,000,000 to 19,000,000 S/m was not entered as a separate property.
  - The brinell_hardness benchmark name is not in property-canon.yaml. The Brinell range is recorded with that short snake_case name, as in the 2017 profile.
  - The USGS 2026 aluminum summary read here does not mention a critical-minerals list, so no critical-list entry is recorded.
  - Radiation effects, atomic oxygen erosion, outgassing and cryogenic properties were not looked up for this grade.

    line: 5019 is a wrought aluminium-magnesium alloy, EN AW-5019 or AlMg5. Magnesium is the main alloying element at 4.5 to 5.6 wt%, with manganese, chromium, iron, silicon, zinc, titanium and copper as minor elements (Bikar listing, EN 573-3 limits). The sources read here do not describe how the product is made, and the composition below is the standard range, not a measured value.
    parts:

        symbol: Al
        share: remainder (balance of the composition)

  risk_groups:
    - title: For people
      level: 1
      verdict: Dust, fume and skin warnings
      lead: The Hydro safety data sheet for the 5xxx series gives dust, fume, skin and environmental warnings. No health data for 5019 alone were found.
      points:
        - label: Machining dust
          line: Metallic dust may ignite or explode, and dusts and fumes can cause metal fume fever (Hydro SDS, 5xxx series).
        - label: Skin and inhalation
          line: The same sheet classifies the 5xxx product as a skin sensitiser (H317) and as suspected of causing cancer by inhalation (H351).
        - label: Environment
          line: Small chips, fine turnings and processing dust may be toxic to aquatic life, according to the same sheet.
    - title: If it fails
      lead: The failure routes found in the sources are dust ignition, poor brazed joints and surface corrosion in service.
      points:
        - label: Brazing
          line: The supplier rates hard brazing poor with and without flux, and soft brazing with flux poor. Friction soldering is rated acceptable.
        - label: Corrosion
          line: The supplier rates seawater and weathering resistance very good. No test result for 5019 was found.
    - title: Handling and storage
      points:
        - label: Specify temper and form
          line: Strength ranges differ for H12 rod, tube and wire, H24 tube, rod and wire, and the 0 to 30 °C values, so state the temper and form before comparing figures.
        - label: Dust control
          line: Keep machining chips and fines under control, and avoid breathing dust or fume, following the Hydro SDS.
  why: 5019 is a magnesium-rich aluminium alloy for wrought products. Supplier data give a density of 2.64 g/cm3, a tensile strength of 270 to 350 MPa in H12 rod, tube and wire, and 300 to 380 MPa in H24, with seawater and weathering resistance rated very good. The supplier also calls the alloy food safe. The sources read here name no aerospace or space application for this grade.

      line: The H12 listing gives a thermal conductivity of 110 to 140 W/(m·K) at 20 °C.
    - label: Sea and weather
      value: Very good (supplier rating)
      line: The H24 corrosion table rates seawater and weathering resistance very good. No test conditions are given.
  compare: 5019 is a magnesium-rich aluminium alloy with a density near 2.64 g/cm3 and a tensile strength of 250 to 385 MPa across the forms and tempers listed. The sources here give its density, stiffness and thermal figures only for this alloy, and they do not compare it with other grades numerically.

  handling:
    - Specify the temper and product form, because the tensile ranges differ for H12, H24 and the 0 to 30 °C values.
    - Keep machining dust and fines under control. Metallic dust may ignite or explode.
    - Do not rely on hard brazing. The supplier rates it poor.
  good_for:
    - Wrought rod, tube and wire where seawater and weathering resistance matter, with the supplier rating very good for both.
    - Parts that must be food safe, as the H24 supplier page states, with no further food-contact data read here.
  watch_out:
    - Brazing is rated poor by the supplier, so brazed joints may be weak.
    - No yield strength was found for any temper, so yield-based design values cannot be taken from these sources.
    - The corrosion rating is qualitative and has no test conditions behind it.
    - The hazard classes apply to the 5xxx family, not to 5019 alone.
  verdict: 5019 is a corrosion-resistant Al-Mg wrought alloy by supplier rating, with a tensile range of about 270 to 380 MPa depending on temper. The sources here are thin on yield strength and on any space or flight use, and the hazard data are family-level.
