I also think that Vibranium is harder to come by for diplomatic reasons not to mention of how expensive it is ( Eventhough Stark is filthy rich and SHIELD might have government funds ). In the comics version of Project Rebirth ( I guess Earth 6:16 ) Captain America's shield is made from an alloy of steel,vibranium, and an "unknown catalyst." ???
