We could use your honest opinion on this object. A friend suggested meteorite, even though there wasn't much fusion crust left on it. We did some research online an the closest resemblance was the hexahedrite with the blue fusion crust. We also did some home tests; this is what we know:
The dull grey/blue exterior was grazed with a small grinding wheel. It now looks like shiny new metal with only a few spots that show rust after getting it wet. Has weak magnetic attraction, leaves light grey streaks on non-glazed porcelain, heavier than other rocks of it's size, looks like chrome inside when sawed, but has micro bubbles when chipped off. After chipping off a small piece, we hit with a hammer. It crushed like stone with some very shiny specks that flattened out, and the rest turned to powder. All particles were picked up by a magnet.
We have looked at thousands of pictures of meteorites and meteor-wrongs, foundry slag & ore, and we only found three that were close. All of which were confirmed meteorites. Unfortunately, origin and history are unknown. What do you think? If not meteorite, do you have a clue of what it might be? Thank you for your time.

The results you gave sound a lot like SEM-EDS (scanning electron microscope with energy dispersive spectroscopy) results. Aside from having access to such a machine, the key I've found is the analyst interpreting the results. If you have the spectra charts and pictures showing the areas they were taken from, along with parameters used, that would be helpful. For me, they'd be interesting, but I'm pretty clueless there. Posting them in a materials forum or similar might yield you results; particularly if the person has seen such a similar animal previously.
