金属材料广泛应用于医学领域，不仅用于骨科植入物，还用于心血管设备和其他用途。世界各地不断开发用于生物医学的新型合金，以减少植入过程中的腐蚀、毒性和断裂，并增加界面和动态组织相容性。钛合金的研究主要集中在开发钛合金上，尤其是杨氏模数低到皮质骨的P型钛合金。无镍合金也是防止镍过敏的必要条件：无镍奥氏体不锈钢和形状记忆合金被开发出来。为了提高生物相容性，有必要对表面形态和表面处理或改性进行控制。
Metallic materials are widely used in medicine not only for orthopedic implants but also for cardiovascular devices and other purposes. New alloys for biomedical use are developed all over the world continuously to decrease corrosion, toxicity and fracture during implantation and increase interfacial and dynamical tissue compatibility. Most of efforts are made to develop titanium alloys, especially in P-type alloys whose Young's modulus is as low as cortical bone. Nickel-free alloy is also necessary to prevent nickel allergy: nickel-free austenitic stainless steels and shape memory alloys are developed. To increase biocompatibility, the controls of surface morphology and surface treatment or modification are necessary.
