CANADA: An American corporation that produces aircrafts has released a video that shows a lightweight material called microlattice metal. Dubbed as the world’s lightest metal, the microlattice is 100 times lighter than Styrofoam, and is so lightweight that it can be balanced on top of a dandelion, scientists say.
Boeing, an aerospace company known for its airplanes, rotorcraft, rockets and satellites, released a video of the microlattice metal first developed by a team of scientists from the University of California, Irvine, HRL Laboratories and the California Institute of Technology in 2011.
The microlattice is an interconnected criss-cross of hollow tubes positioned in diagonal patterns. Dr. Tobias Schaedler, lead author of the study published in the journal Science, said that each polymer structure has a thickness of 100 nanometers which makes it 1,000 times thinner than a strand of human hair. The initial prototypes for the microlattice were made from a nickel-phosphorus alloy.
“By changing the structure at these levels you get completely different properties from the bulk material, which is a very powerful concept,” said Schaedler.
