Cybertroid alloy
From Transformers Wiki
Cybertroid alloy is a type of Cybertronian alloy used in the star drive onboard the Nemesis.
Since the Nemesis was powered by a one-of-a-kind energy maximizer called the Heart of Cybertron, it is unclear whether cybertroid alloy would be commonly found in stardrives, or if this one was special.
