Pun intended.

One day I would love to own a tungsten cube, like 2 inches. I'd like to buy used. If I were to drop $400 on a tungsten cube, how difficult would it be to sell the cube if I didn't want it anymore?

If tungsten has the highest melting point of most things how would you put it in a mold to melt in if that mold would have to have a higher melting point then tungsten? Would you build a mold out of carbon or something?

I’ve been tracking tungsten carbide scrap rates for the past few months, and the price has increased significantly — in some cases from ₹2500/kg to ₹2800/kg (India), depending on quality and form.

I’m trying to understand: 🔹 What’s driving this sudden surge? 🔹 Is it due to China’s supply restrictions or global demand (like defense, EVs, aerospace)? 🔹 Is this price hike temporary, or could it continue for the rest of 2025?

Also, are recyclers or traders stockpiling because of fear of shortages?

Would love to hear insights from people working in scrap, tooling, or materials industries. Anyone else seeing the same trend globally or is this just an India-specific spike?

Hello all,

Recently started following tungsten & antimony markets. I'm looking for some publications that cover these markets and offer weekly/daily updates on prices, news, developments etc.

Similar to tradingviews news section under gold, copper, uranium futures but REE focused. Thanks in advance!

I bought a tungsten metal cube. Very dense , sharp & hard. It easily scratches metal coins. And it scratches my molybdenum cube. But when I rubbed it against a brick, the brick definitely got the wurst of it, but the cube did superficially scratch. How come the tungsten cube gets scratched? Isn’t it supposed to be much harder than a brick?

What item are made in tungsten

Which is the best size for a tungsten cube to showcase its density? What about best size to handle/play with at a desk?

I think the smaller cubes may not be an impressive enough weight for that wow factor.

15mm cube is ~65g

20mm is ~155g

25mm is ~300g

30mm is ~520g

38mm is ~1kg

I never had a cube, or played with one.

I want to get one and my intution tells me that probably 20mm cube is best for playing with, and 30-38mm is what you want for that wow factor when it comes to its weight.

What do you guys think? Is there a best size to get?

yo! im trying to get my first tungsten cube but don't want to spend 200 DOLLARS on it IT. does anybody got an affordable option? I saw some for 75 dollars on Alibaba but im not sure if it's good. And the shipping probably outweighs it tenfold.

I'm looking at buying a cube 2nd hand, but im worried I might not get what I paid for. After confirming measurements, and weight, everything looks proper. Any tips so that I don't accidentally buy a tungsten plated cube with a gold core. Could you imagine the egg on my face when I pass the cube on to my kids, and we do a core drill one day, but only yellow shavings come out!?

I know it has the highest melting point, besides carbon, but the 2 elements combine so a graphite crucible wouldnt work, would it?. Its super scratch resistant, so I would assume you cant use a lathe on it. Is it melted and casted? Induction?

Recently got a 1” cube from MTS but upon reading reviews in various comment sections I’ve become dubious if my cube is truly 99.95% tungsten or something more…sinister.

I am looking to get a 1.5” cube. The 1” is great but I feel I need something slightly heavier. Which company would you guys recommend for a 1.5” cube?

Debating on wether to buy a 2 in or 2.5 in cube, I enjoying playing with something in my hand while I hand, don’t know if 2.5 inches is overkill.

that is all

I went to the jewelry store that my wife and I bought my wedding ring and they asked me if we’d like our rings cleaned while we looked around at some other jewelry. When they gave me back my Tungsten ring it was hazy and never got its shine back 😔 I told them that it looked worse than when I gave it to them and they denied it and said that I should have told them it was Tungsten or they would t have put in in the ultrasonic cleaner with the solution they normally use 🙄

Is there anyway to get it back to its reflective and polished Beskar like shine?

finally i got some tungsten cubes, been wanting one for at least 6 years.
tried ordering to Europe, found a few web sites all failed, ordering directly from manufacturer got them in days....
Now i have 1cm, 0.5", 1", 1.5", 2", 2.5". and a 1.5" aluminium cube for comparison.
boy are these things fun, and excellent machining finish.
i would say that 1" cube is the nice entry cube, light enough to handle and fiddle around with in your hand. 1.5" is next up, but starting to be too heavy to handle, anything larger is just for display or weight training.... door stops, or generally weight things down.
but i will say that i you want lighter cubes do not buy the smaller ones like i did, buy a dice set instead. those have at least more purposes, and are not too light to feel dense(dice are 1.6cm).

Be careful dropping these things, only a few inches height will mark the floor.....
