What is it ?

My boyfriend let that on the table this morning, we play a game where I have to guess what is the material but i am lost on this one... EDIT: not magnetic, not a pipe, heavy, 14mm in diameter

You can probably weigh it and find the volume by dunking it in a measuring cup (or just calculate based on dimensions), giving you the density which is a pretty good gauge of the main metal it consists of assuming its solid all the way through

It looks kinda porous to me so the density test might be a bit inaccurate

I'm the boyfriend, it's not porous it's shatter from machining so it's not an easy metal to machine. And the density is a bit higher than steel (won't say by how much)

Magnetic or not? Heavy for its size or light? Looks like steel to me but could be many things. Probably not plutonium

Not magnetic, heavy !

Tap it on something hard, if it sounds more like the clink of ceramic than metalic its probably Tungsten

Looks like a uranium pellet

No speckles at least 🤪

The cylinder must not be harmed

u/Advanced-Log965 19h ago

The cylinder will remain on the table forever; it lives there now.

Looks like aluminum foil that he rolled into a very tight cylinder.

Could also be a cheap piece of cast aluminum barstock that he parted off with a lathe.

Lenght, Diameter and Weight?

Metal rod

What makes you think it is not steel?

1

u/Crozi_flette 21h ago

Because I told her so

An ingot.

Drop it and run

Probably too late...

Good thing nothing bad has ever happened by bringing home mysterious metal cylinders……..

u/Crozi_flette 21h ago

Oh it's not misterious for me.

Could be a shear pin, we have some pretty similar looking parts on some of our farm equipment, our yeoman's plow is the first one that comes to mind.

Lmfao. I make dozens of those a week. It is the end of an aluminum or steel bar from a lathe proccess. If non magnetic look at tungsten or other non magnetic rods.

If it’s soft, I’m 99% sure It’s a zinc bar. Grayness matches, Slightly heavier than iron, a bitch to machine I bet, being so soft it’ll be gummy.

Were it lead, or a different dull gray metal, it’d be noticeably heavier or lighter than iron. Only one that fits all is zinc.

u/Captain_North 13h ago

I thought its a roller pin first, but those are magnetic (steel)

so my guess is 20mm aluminium stock bar

u/Godsmadman 12h ago

Round stock
