Aluminum 6061 T6 T651

T6 temper ***1 has an ultimate tensile strength of at least *2,**0 psi (**0 MPa) and yield strength of at least *5,**0 psi (**1 MPa). More typical values are *5,**0 psi (**0 MPa) and *0,**0 psi (**5 MPa), respectively.[3] In thicknesses of 0.**0 inch (6.*5 mm) or less, it has elongation of 8% or more; in thicker sections, it has elongation of *0%. T**1 temper has similar mechanical properties. The famous Pioneer plaque was made of this particular alloy. The typical value for thermal conductivity for ****-T6 at *0°C is around **2 W/m K. A material data sheet [4] defines the fatigue limit under cyclic load as *4,**0 psi (**0 MPa).
