Introduction In modern history metals have been used as implants since more than 100 years ago when Lane first introduced metal plate for bone fracture fixation in 1895 Lane 1895 . In the early development metal implants faced corrosion and insufficient strength problems Lambotte 1909 Sherman 1912 . Shortly after the introduction of the 18-8 stainless steel in 1920s which has had far-superior corrosion resistance to anything in that time it immediately attracted the interest of the clinicians. Thereafter metal implants experienced vast development and clinical use. Type of metal used in biomedical depends on specific implant applications. 316L type stainless steel 316L SS is still the most used alloy in all implants division ranging from cardiovascular to otorhinology. However when the implant requires high wear resistance such as artificial joints CoCrMo alloys is better served. Table 1 summarized the type of metals generally used for different implants division.
