Bouncing bearings on liquid metal


Advertising is advertising. I think we all know that.

And the advertising demonstrations set up in sporting good stores aren't always the truest indicators of a particular piece of equipment's final performance. Yes, the materials shown probably perform the specific functions being demonstrated very well. Here we can see that the rebound of a metal ball off of liquidmetal's proprietary alloy as compared to the rebound from a titanium surface.

We have to assume that all the other variables - material thickness, cold or hot treating perhaps - are the same between the materials and that the two metal balls are also the same. If so, we can safely say that the liquidmetal does, indeed, provide a greater rebound (coefficient of restitution if I remember my physics correctly). Now, what does that mean on the surface of a golf club, in a tennis racket, or as a fishing pole?

That I can't definitively say from the limited data I have before me. I am glad, though, that their website does provide a little of the science behind the fact that the alloys possess ' an "amorphous" atomic structure, which is truly unique. By contrast to the crystalline structure, no discernable patterns exist in the atomic structure of the unique Liquidmetal alloys. As such, properties superior to the limits of conventional metals can be achieved.'

Has anyone actually used anything from the liquidmetal line?
