Abstract

Metallic materials are widely used as an implantable materials, especially in the field of load bearing applications. Stainless steel, Co-Cr alloys and titanium (Ti) based materials are the most common materials in this vital field. Recently, Ti alloys are attracting much interest as biomaterials due to their superior corrosion resistance, better mechanical properties such as remarkably high specific strength, low elastic modulus, and excellent biocompatibility. The present paper discusses the different kinds of metallic materials for biomedical applications in view of their challenges and opportunities.
