the standard
in the alloy 5083

Medium-strength rolled plate

Alloy: EN AW-5083 (AlMg4,5Mn0,7 – 3.3547)

Type of alloy: non heat treatable

Temper: H111

Surface: mill-finished or brush-finished

  • good anodising capability
  • very good corrosion resistance
  • very good weldability
  • good machinability

Medium-strength rolled plate EN AW-5083 (AlMg4.5Mn0.7) is used almost universally in almost all areas of the capital goods industry because of its many beneficial properties. Under certain loads and temperatures >70 ° C, there is a risk of stress corrosion cracking (SCC).

Food industry

Rolled plates made of EN AW-5083 are safe in contact with food in accordance with EN 602:2004. For this reason, this material is used in a variety of applications in industrial plants of the food industry.

Expert tip

The tolerances for thickness and flatness are very wide in rolled plates. For example, a 20 mm thick plate has a thickness tolerance of ± 0.7 mm. The flatness is specified as a percentage and is calculated longitudinally (always in the rolling direction!) and in width (always transverse to the rolling direction!). A 20 mm thick slab in format 1,520 x 3,020 mm may vary by 0.2% = 6.04 mm and 6.08 mm in width from the flatness.

In comparison, G.AL® C250 in 20 mm thickness: thickness tolerance: ± 0.1 mm, flatness: 0.13 mm.
