ALUMINUM 6061 TUBE AND PIPE MECHANICAL PROPERTIES

Aluminum 6061 drawn tube and pipe material properties for T6/T4 tempers are given below.

Notes:

• e — edge distance (in loading direction), D — diameter of the hole.
• If direction of use is unknown, use the lesser of applicable longitudinal or transverse properties.
• Welded structures typically have lower allowable stresses. Heat from welding softens the HAZ. Typical welded 6061-T6 (ksi): F_tu 24, F_ty 20, F_cy 20, F_su 15, F_sy 12, F_bru 50, F_bry 30.

Definitions:

A Basis: Lower of T99 or specification minimum (S-basis). T99: ≥99% of the population meets/exceeds the value with 95% confidence.

S Basis: Minimum values per specification; statistical basis not defined.

Longitudinal Direction: Parallel to the material flow (grain direction).

Long Transverse: Transverse direction with the largest dimension (width).

Short Transverse: Transverse direction with the smallest dimension (thickness).

Solution heat treatment: Heat, hold to dissolve constituents, then rapid quench.

Modulus of elasticity (Young’s modulus): Slope of stress–strain curve within the proportional limit.

Poisson’s ratio: Lateral strain / longitudinal strain under uniaxial stress in the proportional limit.

Shear stress: Stress acting parallel to the cross-section.

Stress: Force per unit area.
