2011 aluminum block bar

Jun 10, 2023

2011 aluminum block bar, American deformed aluminum and aluminum alloy.

The alloying element of 2011 aluminum block bar is copper, which is a free-cutting alloy containing traces of lead and bismuth. It has high strength and good cutting performance, but its corrosion resistance is poor. It is commonly found in bars, pipes and wires. 2011 aluminum alloy is used to manufacture screws and machined products that require good cutting performance.
