General Info About 6061 Aluminum Sheet

This aluminum grade is considered one of the most popular general purpose aluminum alloys. It’s versatile and heat treatable with moderate to high strength, excellent corrosion resistance, and excellent weldability. It is a commonly extruded alloy that can be machined and anodized, leading to use in a wide range of applications across industries. Its primary alloying elements are magnesium and silicon.

More Details About 6061 Aluminum Sheet

  • Advantages/Disadvantages

    This aluminum grade has excellent corrosion resistance, machinability, excellent surface quality, and good weldability. After heat treatment, this grade’s strength equals that of a low grade steel and can be used for moderate to high load bearing applications. It is also ideal for applications that require a combination of good strength-to-weight ratio, surface finishing, and corrosion resistance. One disadvantage of this grade is that it is not as easily formed.

  • Industries

    It is often used in the construction, architecture, and marine industries.

  • Applications

    This grade is often used for structural framing, moldings, fire ladders, a variety of welded assemblies, valves and fasteners, truck and bus bodies, crossmembers, brakes, wheels, receiver tanks, sail boats, bridge components and piping.

  • Machinability

    It has excellent machinability.

  • Welding

    It has excellent weldability.

  • Heat Treatment

    It is heat treatable.

Frequently Asked Questions

  • What are the properties of 6061 aluminum sheet?


    As part of the 6000 aluminum alloy series, this grade is alloyed with magnesium and silicon. 6061 has a higher percentage of magnesium than silicon, which leads to its good strength-to-weight ratio, and lower formability. Its finer grain makes it suitable for anodizing, leading to excellent corrosion resistance.

  • What is the density of 6061 aluminum sheet?


    6061 aluminum has the same density as pure aluminum, 2.7g/cm3, 0.0975 lb/in3.

  • What is the strength of 6061-T6 aluminum?


    Tempering aluminum increases the strength. 6061-T6 aluminum has an ultimate strength of 310 MPa (45,000 psi) and a yield strength of 270 MPa (39,000 psi).
