Tungsten Cube W 99.95% Wolfram Element Cube Pure 10mm Density Cube for Element Collection Periodic Table Hunter, and More (0.39", Tungsten)

This solid cube of tungsten is impressive and weighs exactly as specified. The density is impressive and there has been 0 corrosion and it has no magnetism so I wager its legitimate tungsten.. do not drop on phone screen by accident, will scratch lol. No complaints on this solid yet somewhat useless cube of tungsten. Im going to begin collecting elements and this makes a good addition to my collection.

It's a very good cube of tungsten. Super heavy despite size. The edges are sharp so I had to be careful but it's good. A perfect tungsten cube.

I now have 10 element cubes from this manufacturer and so far, this is the densest. Almost twice the density of lead (Pb). I have enjoyed collecting other cubes from the same company because they all seem very well made. I plan to purchase other elements to add to my collection.

The product itself is great and high quality. The problem I have with it is probably my fault in that I expected the weight in the hand to be more noticeable between this and an aluminium cube if the same dimensions. I can still use them to get the density point across by utilising scales. However I find that most people are not that shocked by the density difference when just holding them in their hands. I have held larger examples of tungsten and aluminium in my hands and the difference in density is made much clearer by those larger cubes. I was hoping to get similar impact at a lower price.

Small, well made with nice sharp edges. I do love these little element samples for various purposes.

Ok so it’s a little pricy….but it’s so cool! The weight of this small cube truly is mind bending. I cannot express how cool it is to hold this in your hand. This is proudly displayed on my desk and is a great conversation piece!

These are cool for the STEM kids. It helps complete the other set. A little pricey but of course will last a couple lifetimes. They are small but when you get them all it makes for a nice nerd display.

I bought this Tungsten cube and an Aluminum one - the heaviest and lightest metals you can hold in your hand safely. The contrast is amazing.

Smaller than I mentally realized, but exactly as described. Fun product that confused the delivery

Heavy cube 10/10 I love picking it up and feeling more weight than expected of a cube of this size. Great fun.

A small but perceptibly heavy cube, the density is about 19.6. I only wish I'd ordered a bigger one for the extra oomph.

Very Nice little sample. Be aware that this is a 'sharp' metal and the cube has been cut accurately which gives sharp edges. If you plan on handling it a lot then I would suggest a gentle sanding on the edges and corners. I purchased this so I could show people what a cubic centimeter of Gold feels like. Tungsten (19.25) and Gold (19.30) have almost the exact same density. I then tell them that the little cube they are holding represents more than $2,000 Canadian in 24K Gold. Fun Factoids.

Can confirm that it appears to be tungsten. With my non-lab grade tools I found the cube is 10.015 mm per side with a mass of 18.5g. This works out to a density of 18.6. The accuracy of my scale is likely at least +- 0.5 grams or more. With such a high density there very few other elements it could be beside tungsten,.
