Duritanium polyalloy

Duritanium polyalloy was a strong type of alloy used for construction and based in duritanium.

An alien probe destroyed by a Cardassian ATR-4107, dubbed Dreadnought, was composed primarily of duritanium polyalloy. When the debris was later discovered by the USS Voyager, it was noted that very few weapon types were capable of damaging a spacecraft with a duritanium hull to that extent.
