  "summary": "5083 is a wrought aluminium-magnesium alloy with 4.00 to 4.90 wt% magnesium. Its suppliers describe it as the strongest of the non-heat-treatable aluminium alloys and as highly resistant to attack by seawater and industrial chemicals. It is used for ships, pressure vessels, vehicle bodies and rail cars, and the suppliers advise against use above 65 °C.",
