they have to doll up the name... just say what it is! (so we don't have to feel like idiots because we dont' know what ZR 9000 is!
Using "alloy" for "aluminum" is stupid but they've been doing it for many many decades. They have to mix things with aluminum because the metal would be much too soft otherwise. Your chainrings might wear out in a week if they were pure aluminum. There are so many ways to alloy it that I guess the manufacturers want to brag on their way and give it a fancy name.
