Why this rock is probably not a meteorite:

This metal thing was found in Ohio by someone using a metal detector. An iron meteorite would never have such a non-aerodynamic shape; the aspect ratio (length/width) is too large.  Like meteorwrong 122, it has a flat "bottom." Also, it's broken. Iron meteorites are extremely hard. One shaped like this could not be broken. If it could, it would not have the texture of the broken faces in the bottom photo. Finally, the finder had it chemically analyzed. It is 78% iron and 10% nickel, but its 19% chromium. That's a man-made composition. Iron meteorites have <0.02% Cr.
What is it?

Something man made, molten metal poured onto a flat surface.
