From the Bench
Slot size matters more than diameter. A slotted bead will seat on a jig hook that a round bead of the same diameter will never clear. At the top end, 4.5mm caps out around a #4 and will not fit larger hooks.
On the Metal
No tungsten bead is pure tungsten. Pure tungsten is brittle at room temperature and cannot be drilled and finished at this scale, so every tungsten bead on the market is a heavy alloy. Ours runs 95% tungsten with a nickel-iron binder, which is the high end of that range. You get the density without the brittleness.
