Metals and their alloys are used in medicine especially for hard tissue replacements where special properties are required (e.g. biocompatibility, low Young’s modulus or corrosion resistance). Another important group is biodegradable materials for fixation devices and stents where the corrosion rate and biocompatibility are essential properties. Stainless steel or Co-Cr-Mo alloys are still used despite their lower biocompatibility and high modulus (~210 GPa). Titanium and its alloys (Ti6Al4V) have good biocompatibility, corrosion resistance and lower modulus (~110 GPa). On the other hand newly developed beta-titanium alloys are promising materials due to their combination of excellent biocompatibility, high strength (> 1000 MPa), very low Young’s modulus (~50 GPa) and corrosion resistance. These alloys were developed primarily for bio-applications and they seem to have the best known combination of properties for this purpose. Another important group of metallic biomaterials are biodegradable materials. They are used for short-term applications and eliminate the problems and risks of reoperations. This paper is a short insight of currently used and developed metallic biomaterials.Keywords: Biomaterials, metals biocompatibility, mechanical properties
