Aluminum (3.5e Equipment)
From D&D Wiki
Aluminum is a very light and very expensive metal.
A weapon made of aluminum is one-third the weight of a weapon made of steel. Any metal weapon may be made of aluminum.
Pure aluminum is twice as valuable as gold because of the extreme temperatures required to smelt it. A pound of raw aluminum is worth 100 GP. However, pure aluminum is easier to work. Therefore, an aluminum weapon costs half what a steel weapon would cost plus an additional 100 GP per pound. Since the cost of aluminum per pound is for the aluminum itself, not the crafting, do not factor it into Craft checks; the cost to construct an item of aluminum is 1/6th the item's base price, but the smith must have sufficient raw aluminum.
Aluminum has 15 hit points per inch of thickness and hardness 6.
