Background: Cu-Al-Ni shape memory alloys (SMAs) possess two-way shape memory effects, superelasticity, and damping capacity. Nonetheless, Cu-Al-Ni SMAs remain promising candidates for use in biomedical applications, as they are more economical and machinable than other SMAs. This study investigates the concentrations of metal ions (Cu²⁺, Al³⁺, and Ni²⁺) potentially leaching from these alloys to assess their toxicity and selective leaching characteristics. Methodology: The investigation involved in vitro assessments, focusing on the corrosion behavior and biocompatibility of Cu-Al-Ni SMAs. The research was aimed at establishing the correlation between ion concentration and negative biological responses. Results: The findings indicate that while the rapid solidification process enhances corrosion resistance, the release of metal ions can compromise biocompatibility, presenting a risk in biomedical applications. Therefore, ensuring that Cu-Al-Ni SMAs meet biocompatibility standards is essential for their safe utilization in medical devices and implants.
