Aluminum Cold Finished & Extruded Rod & Bar Like 2011, this is a general purpose screw machine alloy. Higher strength than 2011-T3. Good machinability and machined surface finish capability. A highstrength material of adequate workability. Has largely superseded 2017 for structural applications. Comparable strength to some mild steels.
