# Ultra-Flexible Hip Implant Materials This Superelastic Alloy Could Increase Hip Implant Success By Michael Hemsworth | Published 2022-06-01 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/superelastic-alloy References: [newatlas](https://newatlas.com/medical/superelastic-metal-alloy-bone-implants/) & [tohoku.ac.jp](https://www.tohoku.ac.jp/en/press/new_flexible_and_tough_superelastic_metal_alloy.html)  This superelastic alloy has been developed by a team of scientists at the Tohoku University in Japan as a solution for use within [implants](https://www.trendhunter.com/trends/monogram-technologies) 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](https://www.trendhunter.com/trends/titanium-jewelry) 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](https://www.trendhunter.com/trends/trainers-choice).
