Jin'ha

The Jin'ha were a mysterious species famous for their work on the lightsaber resistant cortosis. Obi-Wan Kenobi and Qui-Gon Jinn fought an army of Jin'ha in order to free the captive Jedi Masters Eeth Koth and Plo Koon.

The Jin'ha also sold some of their cortosis ore to the Trade Federation, which crafted it for their experimental assassin droids.
