Aluminium round bar, manufactured in alloy 6026 T6, a versatile alloy with balanced characteristics of strength, suitability for anodising, corrosion resistance and weldability. Suitable for all types of hydraulic, pneumatic and electronic applications.
In calibrated quality, the tolerances of the bar are tighter, which avoids roughing operations depending on the part to be made.
The Ø8 drawn aluminium round bar is made of alloy 6026. An aluminium alloy belonging to the 6000 family, with magnesium and silicon as the main alloying elements.
This alloy combines good machinability with good corrosion resistance, which can be improved by anodising, as well as medium-high mechanical characteristics.
It is an alloy whose lead content means that its use is restricted in accordance with RoHS regulations.
This aluminium alloy has the following composition:
