The thing is its not 6061 (you'd hope). They are using the widely available (overstocks and cheap) AL6063 for them. Filled with impurity, it barely anodize and so soft and gummy you can write your name on them with a tree branch.
1KG of 6063 = US$1.3
7075 is not available locally. Well, it is 'by name' but the hardness/rockwell is roughly the same as 6061 (as known). Needs import - ask me how I know :/
