The aluminum 6061 alloy is strong, easily machined, and weldable. Aluminum 6061 alloys are doubled the strength of aluminum 6063 alloys. Aluminum 6061 has an ultimate tensile strength of at least 42,000 psi (290 MPa) and yield strength of at least 35,000 psi (241 MPa). In thicknesses of 0.250 inch (6.35 mm) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%. T651 temper has similar mechanical properties. The famous Pioneer plaque was made of this particular alloy.
6061 Aluminum Plate is an aluminum-silicon-magnesium alloy, strengthened by precipitation hardening. This alloy has medium strength, formability, weldability, machinability and corrosion resistance.
6061 Aluminum Sheet/Plate can be processed into varieties of tempers, such as O, T4, T6, T651, etc. Among them, T4 and T6 are the most common ones for their good machanicability and weldability.
6061 Aluminum plate is used for tooling plate, architectural applications, transportation equipment, industrial structure frame, which requires high anti-correction, such as truck, construction, ships, trolley bus, railway transit, bridge railing components, and is useful in welded structural application.

Mg and Si are added to 6061 aluminum sheet/coil, thus, it has middle strength and good resistance to correction. Cu and Zn can also improve the strength of aluminum alloy. Besides, 6061 aluminum sheet/coil probably the most commonly available, heat treatable aluminum alloy. 6061 aluminum sheet/coil can be easily cold worked and formed in the annealed condition. Stamping, bending, spinning, deep drawing are all readily accomplished using standard methods. By adding copper, 6061 aluminum sheet/coil has 40% electrical conductivity.
