Aluminium round bar, manufactured in alloy 2033 T3, an alloy with very good machinability and high mechanical characteristics but which does not contain lead, making it the ideal substitute for alloys 2011, 2007 or 2030. Ideal for complex parts for all types of industries,
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 EN AW 2033 alloy. An aluminium alloy belonging to the 2000 family, with copper as the main alloying element.
This alloy, which contains no lead or tin, has been developed to replace alloys 2011, 2007 and 2030, which do not comply with RoHS requirements due to their composition. With the correct machine parameter settings, this alloy is capable of meeting high machining requirements.
This aluminium alloy has the following composition under standard EN 573-3:
