I also have this cube as part of a set. As a far as desk accessories and toys go it's unique and a fun thing to show off.

If you get the set that has the copper cube beware that the copper one will oxidize and discolor if you touch it a lot.

Gotta say I love the ad copy for the 10 pound cube:

    ADD to your collection! This cube is the larger version of the world famous tungsten cube
    COMPARE the density to our 2.5" Aluminum cube to enhance the experience

I wonder why it is 5% nickel/iron -- availability? Machining purposes?

If you drop it, your floor won't like it. My 2lb one is great though!

I bought a set of 1cm element cubes awhile ago. There is definitely a change of perspective of density when you see several things of one generic size, and yet they are dramatically different weights.

I think it's fairly common to see volume and assume weight. And less volume is often assumed to be a structure issue, like expanded metal vs solid blocks of metal.

I often marvel at the densities of the various heavy metals especially compared to steel. The densest of them like osmium are almost 3x as dense!

I wish I could afford an osmium cube. I guess tungsten is the best cheapest-yet-still-heavy option.

The more accurate title would be "My 95% Tungsten 5% Nickel/Iron Cube"

One excellent application of a block of tungsten is as a bucking bar for metal riveting. Due to its density, tungsten bars can be much smaller than steel ones, easily fitting into your hand, and fitting into tight spaces. I’ve got a number of tungsten bars and use them almost 100% over my steel bars.
