The book that I have lists "typical 6061-T6" as having the following:

Tensile Strength = 45,000 psi
Yield Strength = 40,000 psi
% Elongation = 15

Best bet is to get the data from the manufacturer.  Your supplier will
have data sheets that will give this information.

    This is a UK idea that Rohn looked at several years ago. I don't remember
if it'll handle EHS but hams will NEVER use this system because you need to
buy the terminations and a special tool.

    6061-T6 has a yield strength of 35,000 psi. The figure is for the
material so the particular configuration has little to do with it.
