3-1/2 inch Aluminum Round Bar 2011-T3 is easily machined, average strength, and easily given a good surface finish. 2011 is optimally suited to parts that require lots of complex machining, but aren't necessarily as reliant upon high strength or corrosion resistance. 2011 is typically used for high precision projects, such as screw machines, cameras, clocks, precision gears, and speedometers.
