Zinc

Zinc was an element and a metal.

Among the items stolen by bandits from Adrasta's palace was a zinc candlestick. Torvin took particular pride in this item. (TV: The Creature from the Pit)

The metal used in Vondraxian orbs shared properties with zinc and titanium, but was neither. (PROSE: Trace Memory)

Gallifreyan zinc was one of the strongest metals in the universe. (AUDIO: Pier Pressure)
