Atlas 2011 is a wrought, heat-treatable, aluminum-copper alloy (2xxx series) that also contains small amounts of bismuth and lead. Both bismuth and lead promote high-speed machining by causing the chips to fracture during machining and breaking away from the cutting tool. Atlas 2011 is used in applications where good machinability and high strength are required. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Al-472. Producer or source: Atlas Steels.

Alcoa Toolrite 2011 is a cold-finished aluminum wrought product and is suggested for applications requiring high productivity without corrosion resistance concerns. The alloy has excellent machinability, unexcelled for free-cutting qualities and good mechanical properties. The alloy has excellent machined surface-finish capability. The T451 and T8 tempers offer good deep drilling characteristics. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as machining, joining, and surface treatment. Filing Code: AL-341. Producer or source: ALCOA Wire, Rod & Bar Division.
