# New ‘High-Entropy’ Alloy Is As Light As Aluminum, As Strong As Titanium Alloys

- The research team combined lithium, magnesium, titanium, aluminum and scandium to make a nanocrystalline high-entropy alloy that has low density, but very high strength
- There are a wide range of uses for strong, lightweight materials, such as in vehicles or prosthetic devices
- At this point, the primary problem with the alloy is that it is made of 20 percent scandium, which is extremely expensive.
