Tungsten Cube - 1.5" - One Kilogram

Exactly what it says on the label. It's a 1.5" cube of Tungsten alloy. The densest material you will ever hold in your hand unless you routinely handle gold bullion or work in the nuclear industry. (and the stuff in the nuke industry you probably shouldn't be holding in your hand.) Pure Tungsten has a density of 18.3g/cm^3 (18.25 per wikipedia. 18.3 by places that only go to 1 decimal place) The paperwork that came with this says it has a density of 18.02 g/cm^3 Measuring the cube with my admittedly cheap calipers it is spot on 1.5" on a side. Measuring the weight on my digital kitchen scale I get 1005 grams. By my math That comes to 18.2 g/cm^3 So....either my calipers are off, my scale is off, or there is a transposition typo in the paperwork. Whatever. It's a nice toy. Good paper weight and the fact that it's almost identical to the density of Gold makes it a great conversation piece when arguing with your friends about how the bad guys couldn't possibly haul away that much gold in the heist movie of your choice. EDIT: Having played with it for a while I want to note that according to my digital scale it weighs somewhere between 995g and 1005g depending on the time of day, humidity, and how I'm holding my mouth at the moment. So, +/- half a percent on the stated one kilo mass. Not bad. At the low end it comes in right on the money as far as the documented density is concerned. I'm going to see if I can talk the local high school science teacher into letting me use a balance scale to get a more accurate mass. I'll update if I learn anything new.

It's a cube. Made of Tungsten. You either need it or you don't. If you do, it fits the bill exactly. If you think you don't need it, just consider that you may find yourself without a tungsten cube when you desperately need one. That would be a bad situation. Excellent packaging with critical facts about Tungsten that you can't live without. This one is 1.5" so it's not too big or too small. Don't go cheap, this is the perfect size.

This cube is awesome! I saw one on Youtube awhile back and just could stop thinking about it. I looked around at some other tungsten options, but most had a bunch of ugly engraving on them along with sharp edges. This cube is impeccably machined. There are 0 visible machining marks, and it has a nice shiny brushed finish. The edges are rounded and the corners, while pointy, are not sharp. It also comes with an acrylic stand that holds the cube at an attractive display angle. On to the coolest part though, the weight. This cube is indeed one kilo. The fact that it's so small makes it seem like it weighs muuuch more. Everyone I've shown it to has been amazed. It sits on my work desk and has become my defacto figet toy during boring phone meetings and whatnot. I felt silly when I first made such a frivilous purchase, but as soon as I picked it up and felt the weight that feeling quickly faded away. If you're looking for a tungsten cube, this is the one! P.S. It's not like tungsten will go obsolete. If you ever need to sell it, it'll likely retain almost all it's value. ;)

Very cool, very heavy for its size!

I bought this 1.5" Tungsten cube from Midwest Tungsten Services (MTS) and the very light 1.5" Magnesium version from Forge Solid (which is about 1/3 lighter than aluminum). I have not seen the equivalent Forge Source Tungsten cube in person - but I think it may be helpful to compare the packaging and finish on each of these (different) cubes. PACKAGING This MTS cube came well packaged in a thick roll of foam with padding on all sides. It was shipped in an otherwise nondescript white shipping box. In the package is also a material certification letter, certifying the makeup of the cube and the back side gives some interesting information about Tungsten. It is on letter sized stationary and was folded in such a way in the box as to not make it something you would really display with the cube. The cube was then inside a sealed plastic bag with the company logo and a printed sticker identifying it. In contrast, the Forge Solid cube came in a nice (small), retail quality box with printed pictures of the cube and a description - though it appears they just put the Magnesium cube in the Tungsten box - as the wording on the box was the sales pitch for the Tungsten not Mg cube. No letter or other documents inside - but definitely would make a nicer "gift" product. Also - this one came with a little plastic stand - which I now use for the MTS cube on my desk. Points Forge Solid. FINISH The MTS cube has a nice brushed finish on all sides. The edges are slightly rounded to avoid any sharp sides/corners. One face of my cube has a circular mark across it - the other sides look perfectly finished. Again in contrast, the Forge Solid Magnesium cube does have sharp edges and corners. It is also, surprising not finished. Looks like a piece of industrial aluminum, cut in the shop and sent straight away. All sides have what look like brush or cut marks, and several sides have small / dark spots. Not at all a nice finish. In fairness this Mg cube is not their main business and from the photos I have seen online of the Tungsten version - I believe it would have a finish comparable to the MTS cube - though it may still have the sharp edges. Points MTS VALUE You can get the Forge Solid Tungsten cube on some flash sale sites for around $240. You can also buy smaller versions, and dent/ding versions directly from their website for some savings. The Mg cube is a lot less at around $45. For that you get a cool paperweight in a nice retail box. At the time of this writing the MTS cube is $133 - more than $100 less than the competition. With the nice finish (minus a blemished side) and rounded edges this is the cube to get. Points MTS FINAL THOUGHTS The actual value for 1kg of Tungsten right now is about $23. The rest is finish and packaging. Ultimately what you are buying is an expensive paper weight. I love it - and am very happy with the MTS cube - but if you are planning on gifting this - you will need to come up with your own creative packaging. I wish MTS also made a cheaper and nicer version of the Mg cube - and a small stand would be a great addition.

Totally worth it as someone who has wanted one for a while now. It's beautiful, satisfying to hold, and the subtle rounded corners are appreciated. Truthfully I've kept it with me all day since I opened it. Highly recommend getting one if you're already interested enough to be reading reviews, and I highly recommend this product specifically if you just want a clean cube without engravings. It also comes with a simple but nice little stand, which while not crucial is nice to have.

My life has completely changed now that I have the tungsten cube. It is shockingly dense, and most will never know the power that you, yes you can hold in your hand. I wake up every day in the morning completely refreshed. I don’t even need coffee anymore though I still drink it. I’ve never been able to get much respect in my life. Once I got the tungsten cube though, my wife’s boyfriend started finally letting me get some time on the GameCube. Before he would always hide the controllers so I couldn’t play animal crossing. He has seen the change in me. He can’t push me around anymore. Within a week I got a call from my parents. They said I’m still a disappointment but instead of getting nothing in the will I will be left a $20 subway gift card from 2015 and 2 pairs of jumper cables. I’ve never received such good news in my whole life. None of this would be possible without the cube. Some of you may think, oh I should work on myself to improve my self esteem. Well this cube right here is the shortcut. You don’t need diet, exercise or even to go to college. Everything you need is right here. Cube is love, cube is life.

I've really wanted a tungsten cube for my office desk. It's pricey though, and I used the old adage, wait a month and if you still want it, then you can get it. I waited 8 months for this one but wish I'd purchased it the day I found out about it. The cube is hardy, very dense, and a great conversation piece. When I'm mulling over an issue I'll mindlessly play with it. I think my hand muscles are even getting stronger and more agile because of this purchase. I had a couple of coworkers hold it and they both immediately wanted to buy one. The price is high, ut I think I'm going to have this thing until the end of my days.
