6061 aluminum plate is a precipitation-hardened aluminium alloy sheet, containing magnesium and silicon as its major alloying elements. It has good mechanical properties, exhibits good weldability, and is very commonly extruded (second in popularity only to 6063 aluminum).It is one of the most common alloys of aluminium plate for general-purpose use.
6061-T4
T4 temper 6061 aluminum plate has an ultimate tensile strength of at least 210 MPa (30,000 psi) and yield strength of at least 110 MPa (16,000 psi). It has elongation of 16%.
6061-T6
T6 temper 6061 aluminum plate has an ultimate tensile strength of at least 290 MPa (42,000 psi) and yield strength of at least 240 MPa (35,000 psi). More typical values are 310 MPa (45 ksi) and 270 MPa (39 ksi), http://respectively.Inthicknesses of 6.35 mm (0.250 in) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%. T651 temper has similar mechanical properties. The typical value for thermal conductivity for 6061-T6 at 25 °C (77 °F) is around 152 W/m K. A material data sheet defines the fatigue limit under cyclic load as 97 MPa (14,000 psi) for 500,000,000 completely reversed cycles using a standard RR Moore test machine and specimen. Note that aluminium does not exhibit a well defined "knee" on its S-n graph, so there is some debate as to how many cycles equates to "infinite life". Also note the actual value of fatigue limit for an application can be dramatically affected by the conventional de-rating factors of loading, gradient, and surface finish.
This high-strength, heat-treatable 6061 T4 T6 aluminium alloy plateprovides good formability and weldability and good corrosion resistance. Suitable for a wide variety of structural and architectural applications.
Alloy 6061 aluminum plates are one of the most versatile and widely used of the heat treatable alloys. This wrought tooling plate exhibits excellent machinability, weldability, and medium strength. Though less strong then most of the 2xxx and 7xxx alloys, 6061 is typically selected where welding or brazing is required or for its high corrosion resistance in all tempers. It has exceptional joining characteristics, good acceptance to anodizing and is easily cold worked and formed in the annealed condition.
Applications of high-strength 6061 T4 T6 aluminium plates:
Aircraft landing parts
Marine vessels
Structural architectural parts
Storage tanks
Heat exchangers
