Titanium Ore

Titanium Ore is a new Hardmode Ore that was introduced in the 1.2 patch.

Hardmode Ores are generated upon destroying a Demon Altar or Crimson Altar with a Pwnhammer.

Titanium is the replacement for Adamantite, and unlike its alternate metal Adamantite, Titanium will generate at any level, rather than being limited to lava level and below.

Trivia

 * Titanium's legendary reputation for durability is more based on its inert nature and corrosion resistance rather than its strength; In reality, titanium is no stronger than steel, though it is lighter and far more corrosion-resistant.
 * Even though Titanium Ore is the alternative to Adamantite, Titanium Ore is much rarer than Adamantite Ores and often only spawn in veins of 2 Ore to 3 Ores.
