Aluminum alloy	Si	Fe	Cu	Mg
6005	0.60~0.90	0.35	0.10	0.40~0.60
6063	0.20~0.60	0.35	0.10	0.45~0.90

Tianhe Telescopic Mast Factory claims that they making the masts using the military aviation aircraft aluminum No.6005T5  

Some Rivals in China highly advocate there aluminum pole is best ,, but according to the charts above ,, Tianhemast Factory's 6005T5 aviation aluminum tube is twice more strength in Yeild strength which is key factor to prevent masts from deform or any bend happens than 6063T5 aluminum that other manufacturer used in Wuxi province.
