I thought this object I have was cassiterite, pyrite, wood-tin, or something alone those lines. But with the specific gravity in the 9.13 range it's far too high for that. Any other suggestions?

I found this while working at a farm, a pic link to it is above. I tried to saw it in half once, and all it did was shear the teeth off of the saw. Pretty much 100% it's not man-made.

Are you sure it is a natural material? There are not many common minerals with such high densities. The most likely match is native (metallic) copper, with a density of ~8.9 gm/cm^3.
If it's a manmade material, then there are any number of compounds it might be.
You can check the sources below to see if anything pops out at you.

Note added in response to questioner's comment:
Is the material metallic? -- If you scrape off what looks like an oxide coating, does the underlying material look shiny? Is it malleable or brittle?
Where was the farm?

Aluminum is both an aspect and a mineral (for the answerer above). It has a particular gravity of two.seventy 2 grams in accordance to cubic centimeter. as far as i comprehend elemental aluminum does no longer demonstrate cleavage, and could fracture alongside random planes of weak spot (it really is genuinely extremely malleable and would not damage easily). Its streak is white.

The following common minerals are in your SG range:
Native copper (8.9)
Uraninite (9.0-9.7)
Calaverite (9.35)
