Duly noted, but in my post I copied and pasted for accuracy. "Aluminum Pipe 6061 Extruded T6 Schedule 40"When you say 6061 you also have to specify which temper condition. In condition -0 the material is too soft to use as control tubes, but can easily be bent for piping. -T6 is what you should get for structural applications.
So it is T6, but nobody else I looked at added the word "Extruded" to the description. Wonder what that's about.
