Can aluminum be used to make stents for heart surgery?

Aluminum is not typically used to make stents for heart surgery. Stents are usually made from materials like stainless steel, cobalt-chromium alloys, or platinum-chromium alloys due to their strength, flexibility, and biocompatibility. These materials can withstand the mechanical stress within the body and are less likely to cause adverse reactions. Aluminum, while lightweight and corrosion-resistant, lacks the necessary strength and biocompatibility properties required for long-term implantation in the human body, particularly in critical applications like heart stents.
