Ok being a materials engineer and a diver and knowing how much people are willing to spend on gear, I got to wondering why I haven't seen anyone selling tungsten weights. Tungsten has a density of 19.25 kg/l compared to 11.34 kg/l for lead. So Tungsten is 1.7 times more dense and hence a Tungsten weight would be almost half the size of a lead weight. I know tungsten is alot more expensive (probably 10 times more). I know that caring 24lbs of weight for my drysuit dives is not only alot of weight but also alot of volume and volume = drag, Imaging half the size of weights you currently use (not half the wieght just half the size).
Is anyone at all interested in this? Is this just silly or are divers interested in paying 10times more for soft weight bags half the size? I might consider making some if there is enought interest.
FYI, it really is not feasible to cast tungsten into hard weights (it melts at like 3000F) and would be prohibitively expensive to machine to shape).
