>> Hi All:
>>  My local scrapyard has several pieces of 6105-T6, 12' long,  1.9" dia. 
with
a .109 wall thickness. Was thinking about using it for a boom for a 6 meter
beam. Can't seem to find any tables on the web that explain the specs for
each grade of aluminum, i.e. yield strength, etc., so can compare the
different grades to the ones commonly used by beam manufacturers such as
6061-T6. Can anyone point me to such an animal, or tell me if my boom is
going to hold up or fold up?

    0.1 seconds on google turned up 
http://www.wernerco.com/ExtrudedProducts/alloy.html. It has the same yield strength as 6061-T6. 

    Give it a try. Sounds like it'll work FB; depending on your local 
windspeed and ice conditions, that is. 

Cheers,
