Why this rock is probably not a meteorite:

This is one of the neatest meteorwrongs we've seen. It's metal (it conducts electricity) and it has a coating that looks something like a fusion crust. However, the texture of the metal is too fine grained for an iron meteorite. Big problem: Our analysis shows it to be a an alloy containing mostly manganese.
What is it?

A man-made product, perhaps ferro-manganese.
