  "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.\n",
  "best_for": "Welded structures and marine or chemical service where seawater corrosion resistance matters, at a density of about 2.67 g/cm3",

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."
