Never mind. I found an answer. Please delete.

1- no, you can't mix metals to create a sort of mixed alloy. the weapon is usually made of the metal (like most adamantine weapons) or treated & plated (like silver).

there is an enchantment, metalline if i remember, that allows you to change the material of your weapon i think...

2- natural weapons can't be made with special materials since the material is chosen upon creation of the item. there are items, however, that can add similar effects: savage species has swords & maces you can fit on your tail, adding slashing & bludgeoning damage, as well as being of the metal of your choosing.

1. If you make a suit of armor or weapon out of more than one special material, you get the benefit of only the most prevalent material. However, you can build a double weapon with each head made of a different special material.
2. By definition wouldn't adding metal to a natural weapon make it unnatural?
