Syntactic Foam

This block of metal that is so light, and its density so low, that it floats on water, but despite its appearance, it can also withstand intense pressures. Motherboard visited the laboratory of Nikhil Gupta, an NYU Polytechnic University researcher who is designing some of world’s strongest materials, in conjunction with researchers at Deep Springs Technology. “Syntactic Foam” is a metal that looks and feels solid, but at the edges of any given piece of material, you can see holes because the spherical particles don’t always line up with the edge. These hollow particles, of course is what makes the metal so light. The foam is 44% stronger than similar, aluminum-based foams, while each individual sphere can withstand pressure of more than 25,000 pounds per square inch before breaking – roughly 100-times the pressure exerted by water coming out of a fire hose.
