Dwarven Metal

Dwarven metals are found in the mines of Ironforge, primarily dug up by the Dwarves and crafted into weapons and armor. The primary component of Dwarven metal is "Materium", this is metal has the weight of aluminum but the strength of titanium.

When Materium gets in contact with Blood, it "rusts" much like how Iron reacts with Water. This degrades the Materium by forming an outer coat of "rust" on the outside, this rust is typically Cuprumium or Ferronium.

Controversies
Since Cuprumium has a similar appearance to gold coins, many criminals forge counterfeit coins out of Cuprumium. Dwarven Black Markets are responsible for selling Cuprumium to criminals as the trading of Dwarven Metal has been outlawed unless authorized by the military.
