Duranium

Element Make-up

Duranium is an extremely strong metallic substance used in alloys for hull construction of the starships and space stations of numerous cultures, including Andorians, Cardassians, Ferengi, Humans, Klingons, and Trabe. According to the "Star Trek: Deep Space Nine Technical Manual", duranium is a naturally-occurring ore in planetary crusts such as the crust of Bajor. This would suggest that duranium itself is not an alloy, but rather that there is a family of elements where duranium is the prime constituent. This is further supported by the use of the term "duranium-235," which implies that duranium is in fact an element, one that has an isotope with an atomic weight of 235.

During the Dominion War, the Gallamites were supplying duranium to the Federation for the war effort.

Applications

• The outer hull of NX class starships were lined with duranium.

• Federation Class F shuttlecrafts were constructed with a duranium metal shell.

• Portions of the interior of Galaxy-class starships were composed of solid duranium. It was discovered, in 2366, that Krieger waves were capable of putting a hole in solid duranium, something that is rather hard to accomplish, when one was discovered in the cargo bay of the USS Enterprise, NCC-1701-D .

• The skulls of Soong-type androids are partially composed of duranium.

• Portions of the secondary hull on a Klingon Vor'cha-class attack cruiser were partially constructed from duranium alloy.

Duranium composites

• The Cardassians used two-meter thick duranium composite to shield all the access conduits aboard Terok Nor.

• The emergency hatches aboard Federation runabouts were made of duranium composite.
