Toranium was an extremely strong metal used in Cardassian construction such as on Deep Space 9. Standard phasers were ineffective at cutting through toranium inlays and a bipolar torch was recommended. (DS9: "The Forsaken")

When the USS Defiant posed as the Kobheerian freighter Rak-Miunis, Benjamin Sisko claimed that they were carrying Kobheerian toranium intended for military use on Cardassia Prime. (DS9: "Second Skin")
