This superelastic alloy has been developed by a team of scientists at the Tohoku University in Japan as a solution for use within implants that's durable yet highly flexible. The material was developed and tested, which showed a strain recovery rate that's two-times higher than nickel-titanium alloys and flexibility that's closer to human bone. The material, known as Co-Cr-Al-Si (CCAS), is undergoing a series of additional testing to determine the surrounding reasons why the alloy shows such excellent performance properties.
The superelastic alloy, although only presently under study, shows merit as a potential new material to use in the future that strikes a balance between strength and flexibility. The material is also free from nickel, which could cause an allergic reaction.
