Aluminium rectangular tube 50x25x3 is made from EN AW 6060 alloy. This is an aluminium alloy belonging to the 6000 family, with magnesium and silicon as the main alloying elements.
This aluminium alloy is particularly suitable for the manufacture of extruded profiles and offers an ideal balance between mechanical strength, corrosion resistance and suitability for decorative anodising.
Its extrusion capacity allows the manufacture of profiles with complex and functional designs regardless of their size. This feature, combined with its excellent finish through the anodising process, makes it ideal for all types of decorative elements or visible surfaces with aesthetic requirements.
This aluminium alloy has the following composition under standard EN 573-3:
