Midichloritum

Midichloritum, also known as Tythosium or colloquially as Jedi iron, was an iron alloy used in the creation of Force-imbued swords. Jedi iron naturally occurred in the Tython system, though was also found in limited abundance throughout the Ilum and Sarapin systems. It was named for its ability to channel the Force, hence its popularity among both Jedi and Sith as the base metal of enchanted blades.
