General Info About 6061 Aluminum Angle

It is known to be highly versatile and have a good strength-to-weight ratio. It has good corrosion resistance and is often used in the aerospace and marine industries. 6061 aluminum angle is one of the most common aluminum angle shapes used.

More Details About 6061 Aluminum Angle

  • Advantages/Disadvantages

    6061 aluminum angle has good corrosion resistance, good machinability, and excellent welding capabilities. In addition, it has good strength-to-weight ratio and is highly versatile.

  • Industries

    6061 aluminum angle is used in the aerospace, marine, machinery, structural and ornamental industry due to its high versatility.

  • Applications

    You will find 6061 aluminum angle in medical assemblies, aircraft construction, ship construction, transmission towers, truck trailers, and furniture.

  • Machining

    6061 has good machinability in the T6 temper. However, it is not as easy to machine when it is in the annealed condition.

  • Welding

    6061 has excellent weldability. Gas tungsten arc welding is the most common approach for thinner sections. Gas metal arc welding is recommended for heavier sections. While 4043 can be used for welding, T6’s mechanical properties may decrease.

  • Heat Treatment

    6061 aluminum angle can be heat treated at 990°F. The piece will need enough time to be evenly, thoroughly heated, followed by quenching in water.

    Precipitation hardening can take place at 320°F for 18 hours. The process would be followed by air cooling, followed again by heating to 350°F and, again, air cooling.

Frequently Asked Questions

  • What is the density of Aluminum 6061?


    Aluminum 6061 has a density of 2.7 g/cc (metric) or 0.0975 lb/in³ (imperial).

  • What is the thermal conductivity of aluminum 6061?


    The thermal conductivity, or diffusivity, of both aluminum 6061 tempers is 68 mm²/s (imperial) or 170 W/m-K.

  • What is the tensile strength of aluminum 6061?


    The tensile strength of aluminum 6061 depends on its temper.

    • T6: Ultimate tensile strength of 310 MPa or 45 PSI & tensile yield strength of 270 MPa or 39 PSI
    • T6511: Ultimate tensile strength of 290 MPa or 42 PSI & tensile yield strength of 270 MPa or 40 PSI
  • What is the difference between 6061-T6 and 6061-T6511?


    T6 and T6511 are both tempers, or variants, of 6061 aluminum. They have the same alloy composition, but have different mechanical properties are a result of their different processing. Some notable differences:

    • T6511 has slightly higher fatigue strength (100 vs. 96 MPa)
    • T6 has higher shear strength (210 vs 170 MPa)
    • T6 has higher ultimate tensile strength (310 vs. 290 MPa)
