I don't think that is an issue for this contest. Overloading a package label with too much information is often times worse than not putting enough on it.
This is not a knife, where the type and grade of steal is clearly marked. It is a product using many materials. I suggest focusing on the product and not it's chemical makeup. What type of Aluminum it uses will not be a major selling point.
You may want to ask that in the Tech Forum though. I am sure they would be delighted to answer it. But it is unneeded information for this contest.
