Researchers invent a super-strong aluminium
We’re constantly looking for innovative ways to improve the Springwise experience, and so we’re now introducing BeeLine Reader, a new technology that helps you read more quickly and efficiently. To learn more about BeeLine Reader, an award-winning startup funded by Intel Capital, see BeeLineReader.com.
We have highlighted a number of innovations in construction technology, including a method for creating an ultra-thin, curved concrete roof and paint that can cool buildings. Up to now, however, there have not been many options for replacing steel as the metal of choice in construction. Steel is strong, but it is also heavy. Aluminium alloys are much lighter, but they are also softer and have lower mechanical strength. This limits their usefulness in industries such as construction, and automobile and aerospace manufacturing. Now, researchers at several universities, including Purdue University and Rice University, have worked together to succeed in creating a super-strong, lightweight aluminium alloy.
