Interesting stuff! Density is close to 18.5 (according to my rough measurements), so if it's not pure tungsten it definitely has a lot of tungsten in there. I bought a pure tungsten bar from China (density over 19) and it did not attract a magnet at all, However, these pieces do attract a magnet, which leads me to believe it might have a small amount of metal binder, maybe cobalt, which would explain the slightly lower density and the magnetic attraction All the pieces have a diameter of 9mm. The 3 large cylinders are 12mm long, the two medium ones are 5mm long, and the two smallest pieces are 2mm. (From these dimensions the mass of each piece can be worked out from the density) Hope this helps! I might suggest that sellers include some of this information on the product page because it certainly would help knowing the sizes of the pieces. When I bought these I thought the diameters would be larger.Read full review

I am very satisfied with the tungsten weight set. One of the rating categories doesn't make sense for this product. To me the weights are a measurement tool, and can't (for my uses) possibly be entertaining. Bad category for rating it - not the fault of the product.
