	Is there a difference in microstructure between extruded and drawn aluminum tube? I know the the microstructure will be elongated in both unless artificially aged? Are there other specific differences? Will I be able to differentiate by mounting, polishing, etching and examining with an optical or electron microscope? __________________ ONE TEST IS WORTH A THOUSAND EXPERT OPINIONS

	If annealed after draw or extrusion, the aluminum latice structure will return to "normal". Quenching can be done to harden if you like.
