Aluminium and aluminium alloys have many characteristics which cannot be replaced by other materials. These encompass low density, almost 3 times lower than that of steel, corrosion resistance due to the Al 2 O 3 oxide coating, developing at the surface and easy formability. The aluminium-magnesium alloys, like AlMg3 (AW5754, AA5754), typically contain less than 4 % of magnesium and are not precipitation hardenable. Most of the magnesium contained in the alloys is in solid solution. Therefore, the hardening of the AlMg3, Peraluman 300, is only due to the cold deformation. Lamineries Matthey SA offers AlMg3 (AA5754), Peraluman 300 precision cold rolled strips and foils in different tempers.

Typical uses
Due to its excellent corrosion resistance, the Peraluman 300, AlMg3 (AW5754, AA5754) is widely used in the chemical and food industry as well as for furnishing, aerospace and marine applications. The thin precision strips or foils in Peraluman 300 produced at Lamineries Matthey SA are used for highly demanding applications in the watch or automotive industries for example.
