A fictional metal, most commonly made from cobalt, Chromium, Uranium, and Titanium. It is the play on
words of replacing the T and I off of Titanium, and putting
C and Y as the substitute. It's common acumens is the channel on
YouTube who named himself after the fictional metal. It is super tough, and lightweight making this *fictional* metal great for defending against bullets.
(Note) this metal isn't real,
don't try it, and subscribe to Cytanium for letting me define his name, and letting me talk to him.
