Tianhe Telescopic Mast Factory claims that they making the masts using the military aviation aircraft aluminum No.6005T5
Some of our Chinese Rivals highly advocate that they using the aluminum No.6063T5
Plz see below Chart of the comparison between No.6005T5 aluminum and No.6063T5 aluminum.

The most important key factor of the material is the aluminum yeild strength , when the value is high , that means the aluminum tube have more windload capacity , and won't bend and deformed.
As you can see in the charts , 6005T5 yeild strength is twice solid compare to 6063T5 aluminum.
What does T means in the aluminum No ?
