Tritanium is a miner rebellion armor type. It is the second armor researched by players. It is commonly seen in lower level fleets and is the direct upgrade over Plasteel.
Strategy and Setup
Tritanium is a much stronger and efficient armor in comparison to Plasteel. They are commonly used by low level players replacing Plasteel, equipping them on Talon frigates and Rancor battleships. Lighter variants are more efficient mass to armor ratio than in comparison to Plasteel.
However Tritanium is almost instantly outclassed by Iridium which offers more armor and a rather moderate repair. Tritanium is usually unused in mid-level PvP because it doesn't give enough armor.
Tritanium is a pun of Tri (three) and Titanium. Both metals are very similar, but Tritanium uses other metals (most likely two others) alloyed with Titanium to make it even stronger. As of now, no real-life alloy goes by the name "Tritanium".
