2011 T3 T8 cold drawn Aluminum round bar for aerospace structurals

May 24, 2023

2011 aluminum alloy, American wrought aluminum and aluminum alloy. The alloying element of 2011 is copper. is a free-cutting alloy containing traces of lead and bismuth.It has high strength and good machinability, but its corrosion resistance is poor.It is commonly used for bars, tubes and wires. 2011 cold drawn Aluminum round bar are used in the manufacture of aerospace structurals and machined products that require good



cutting performance.
