RE:Sc-Al alloy beats titanium in price''Let's say that you need light weight or better high-temperature performance and a material that is just 10pc stronger than the best aluminium alloy can be. If you cannot redesign the part, you may be forced into using titanium, which is considerably more expensive. In that case you may pay 10 times as much for only a 10pc improvement. Scandium is a material could help close that gap.
