Metallic biomaterials: types and advanced applications


Metallic biomaterials have found a plethora of applications as medical devices, with stainless steel, titanium and cobalt based alloys employed in most permanent metallic implants. This is due to their favourable mechanical properties, especially fracture toughness and fatigue strength. This chapter reviews the most commonly-used metallic biomaterials, such as commercially pure Ti and Ti-6Al-4 V alloys and Co-Cr alloys and stainless steel, as well as novel metallic biomaterials currently gaining increasing attention, for example bioresorbable Mg alloys and Ni-Ti shape memory materials.
