Aluminium square bar, manufactured in alloy 6082 T6, an alloy with good mechanical properties, good corrosion resistance and suitability for hard and protective anodising. Ideal for structural parts in general.
In calibrated quality, the tolerances of the bar are tighter, which avoids roughing operations depending on the part to be made.
The 50×50 drawn aluminium square bar is made of EN AW 6082 alloy. An aluminium alloy belonging to the 6000 family, with magnesium and silicon as the main alloying elements.
This aluminium alloy is suitable for the manufacture of parts that require medium-high strength and have a medium-complexity design. It also has high corrosion resistance and excellent weldability.
This aluminium alloy has the following composition under standard EN 573-3:
