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 Aluminum alloy square bar are used in the manufacture ofscrews and machined products that require good cutting performance.
LEAD FREE 2011 Aluminum alloy square bar is optimized on the 2011 aluminum bar,using the Sn
Element replace the heavy metal Pb, which meets the EU ROHS environmental requirements and
has the characteristics of the 2011 aluminum alloy.Composition
