Aluminum 6061 drawn tube and pipe material properties for T6/T4 tempers are given below.
Notes:
A Basis: The lower value of either the statistically calculated number T99, or the specification minimum (S-basis). T99 indicates that at least 99 percent of the population is expected to equal or exceed the statistically calculated mechanical property value with a confidence of 95 percent.
S Basis: S-values are minimum values given in the material specifications and standards. Their statistical bases are not defined.
Longitudinal Direction: Direction parallel to the flow in a worked material (grain direction).
Long Transverse: Transverse direction having the largest dimension (width direction).
Short Transverse: Transverse direction having the smallest dimension (thickness direction)
Solution heat treatment: Heating the alloy to a suitable temperature, waiting at that temperature long enough to allow constituents to dissolve and rapid cooling to hold the constituents in solution.
Modulus of elasticity (Young’s modulus): The rate of change of unit tensile or compressive stress with respect to unit tensile or compressive strain for the condition of uniaxial stress within the proportional limit.
Poisson’s ratio: The ratio of lateral unit strain to longitudinal unit strain under the condition of uniform and uniaxial longitudinal stress within the proportional limit.
Shear stress: A form of a stress acts parallel to the surface (cross section) which has a cutting nature.
Stress: Average force per unit area which results strain of material.
