What in the world is this?

[Truth]

I found it perfectly sphere 7” deep no rust marks at all and it is solid.

Do you mean it's a magnet in the sense that it attracts ferrous material... or do you mean it's magnetic... ie is attracted to a magnet?

It’s not stick to a mag

Interesting. An accurate weight and diameter would enable the density to be calculated, which might shed more light on what it's made from.

Milling ball is another possibility. It's not beat up, but then we don't know how much use it might have had.

Is it magnetic?

No the solid Round in helms at all

173.4 mm and 43 mm

Milling ball

Was my guess as well.

I'm with Gene Mean....that's gotta be from outer space. Alien spore? If it hatches, let us know!

I would love to be able to say yes milling ball 100% but this has no seems and was found on private property were a house was. It’s just so round and smooth it’s perfect

Oh and it is not magnetic 🧲

Just a vague memory, but I remember brass ball bearings used in railroad rolling stock many years ago. My grandad worked as a machinist in a car building and repair shop.

173.4 mm and 43 mm

If you mean 173.4 grammes as a weight and 42mm as a diameter, then the ball has a specific gravity of 4.17

Assuming it is metal, not hollow, and not a shell around a core of something else, that pretty much rules out it being made from anything other than: an alloy with a fair proportion of aluminium (which has an S.G. of 2.7); or an alloy with a high proportion of titanium (which has an S.G. of 4.52) and is commonly alloyed with small amounts of aluminium for engineering purposes.

From the lack of corrosion I would guess the latter, and that it’s some kind of bearing.

Okay... I think it is the ball from a giant Alien ball point pen!!! Them aliens really screwed up this time!

I’m going to get batteries for all the measurements tomorrow my batteries are dead

Ok here we go it’s 34.9 mm 137 inches and 175.8 g in weight

Pretty sure it's a "Ben wa ball", go back and find the other one! They come in twos...

 

[E-Trac-Ohio]

Yes, maybe a check valve ball ?

Hey Red-Coat I just put up the measurements on the “What is it?” Video

Thanks. Your revised measurements now give a completely different answer, with a Specific Gravity of 7.9

Although that opens up a wider set of possibilities for what it may be made from, it’s a typical S.G. for stainless steel.

Stainless steel is not always magnetic, despite its high iron content. When non-magnetic, it’s known as “Austenitic” and the lack of attraction to a magnet comes from a combination of what it is alloyed with, together with its consequent crystal structure. Austenitic stainless steel (with 21% chromium and 7% nickel) was first patented in 1912 by Maurer and Strauss in Germany, but there are now numerous variations in composition depending on end use.

In modern parlance the two most common grades are known as 304 and 316. The former may have very slight magnetic properties after being worked, but the latter has no attraction to a magnet. These grades are most frequently used in applications requiring resistance to very high or very low temperatures and/or where resistance to corrosion is important.

Here’s one of many suppliers offering 316 stainless steel balls in 35mm diameter, for which the uses are said to include the following industries: dairy, brewery, paper, pulp, photographic chemicals, inks, synthetic fiber, textile benches and dye stuffs equipment:



I’m not saying this is what you have (and if it is a bearing it has obviously seen considerable use)… but more trying to convey that there’s nothing about it which puts it in the category of “unusual/unexplainable”.

I’m saying that it won’t stick to a magnet

Thank you so much I appreciate what you said and it makes me just love it because it is what it is a metal round ball and it’s also perplexing at the same time. Somethings so normal but it makes me think what is it. Know what they say sometimes it’s the simple things in life
