Researchers discover new welding technology for lighter aircraft
Engineers at the Fraunhofer IWS in Dresden have developed a new method for processing a particularly light metallic alloy. It is intended for use in aircraft construction.

The material called AA5024 AlMgSc is made of aluminum, magnesium and scandium and is about as strong as yet 5% lighter than the aluminum alloys used in aviation. The previous methods however did not make it possible to form AA5024 into the spherical shapes required for aircraft construction. The stretch forming process commonly used for aluminum is not possible with this material.

Although the company plans to further test and develop the method using real aircraft components, it is likely to take some time before it is used in practice.
