T6 temper 6061 has an ultimate tensile strength of at least 42,000 psi (300 MPa) and yield strength of at least 35,000 psi (241 MPa).  More typical values are 45,000 psi (310 MPa) and 40,000 psi (275 MPa), respectively.[4] 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 typical value for thermal conductivity for 6061-T6 at 80°C is around 152 W/m K. A material data sheet [5] defines the fatigue limit under cyclic load as 14,000 psi (100 MPa) for 500,000,000 completely reversed cycles using a standard RR Moore test machine and specimen. Note that aluminum 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.

Chemical composition

The alloy composition of 6061 is:

Silicon minimum 0.4%, maximum 0.8% by weight
. Iron no minimum, maximum 0.7%
 Copper minimum 0.15%, maximum 0.40% 
Manganese no minimum, maximum 0.15%
 Magnesium minimum 0.8%, maximum 1.2%
Chromium minimum 0.04%, maximum 0.35%
 Zinc no minimum, maximum 0.25%
 Titanium no minimum, maximum 0.15% 
Other elements no more than 0.05% each, 0.15% total
. Remainder Aluminium (95.85%–98.56%)


Similar characteristics to 1100 but with higher strength, good workability, weldability, resistance to corrosion. Low cost. Frequently found in pressure vessel applications and chemical equipment.


5086 is the preferred hull material for small aluminium boats or larger yachts. Its high strength and good corrosion resistance make it an excellent match for yachting.[1]

5086 has a tendency to undergo stress corrosion cracking and is not used much in aircraft construction as a result.[3]

5086 has been used in vehicle armor, notably in the M113 Armored Personnel Carrier and M2 Bradley Infantry fighting vehicle.

Chemical properties

The alloy composition of 5086 is:[2]

Chromium – 0.05%–0.25% by weight – Copper – 0.1% maximum
Iron – 0.5% maximum
 Magnesium – 3.5%–4.5%
 Manganese – 0.2%–0.7%
 Silicon – 0.4% maximum
