Technically, the Wikipedia article is called Aluminium oxynitride. Please don't tell the mod. This title (Transparent Aluminum) is more informative and also works as a Star Trek reference, which isn't a bad thing.
I mean, thats more or less correct, though. It just isn't like, what we make interstellar spaceship chassis out of. But we might put it in windows of the ISS.
No, it is not. It is no more "transparent aluminium" than glass is a "transparent silicon".
