Iridium (3.5e Equipment)
From D&D Wiki
Iridium is one of the hardest known metals in existence, but it is somewhat brittle. It can be made into an alloy with platinum to offset its bad qualities. Traders of iridium weapons may take non-coin platinum in exchange for it, at a very good price. It has a white-yellow color.
Weapons made out of iridium are very hard, thus their damage done is increased by 2. Only weapons which are prominently metal can be made of iridium. Weapons made this way weigh one more pound than usual.
Iridium has 10 hit points per inch of thickness and hardness 12.
Weapons made from Iridium are treated like masterwork weapons for the purpose of cost. Other items cost 50 gp more if made with iridium.
