Aluminum Question - Update On Availability

I received some nice samples of the Aluminum and Stainless today in the mail. And majority is 1mm in thickness. Stainless is 0.05.
I was surprised by the fact that they have a nice Black, Maroon, Silver, and Grey. All in all my favorite colors.
Now Id like to know if this aluminum is suitable thickness at 1mm. ?
To me 1.5mm is too thick already?
