A variety of medical titanium alloys independently developed by Shenyang Metal Research Institute, Beijing Nonferrous Metals Research Institute and Northwest Nonferrous Metals Research Institute have been used in surgical implants and vascular stents. In the application of porous titanium alloy, Tangdu Hospital of the Fourth Military Medical University, Northwest Institute of Nonferrous Metals, Shanghai Jiaotong University and other research institutes have designed and manufactured porous titanium alloy implants, which have been widely used in clinic and achieved good results. 4. Conclusion The defect of human hard tissue caused by the aging of population has become a major problem worldwide. China has a large population, the aging problem is very serious, and there are many patients who need rehabilitation surgery with the help of medical implant materials. According to statistics, in the past 30 years, the market of surgical implants in China has developed at an alarming rate. The average growth rate in the past 10 years has been maintained between 15% and 30%, and is expected to continue to grow at a rate of more than 10% in the next 10 years. It can be seen that the market prospect of titanium alloy implants in China is very broad. Although China has done a lot of research work in the research and application of titanium alloy materials for surgical implants and made remarkable progress, compared with developed countries such as Europe, the United States and Japan, there is a big gap in the design, manufacture, processing, equipm ent, surface treatment and technological level of titanium alloy implants. The implants produced in China are difficult to meet the market demand, and most of the high-end implants need to be imported from abroad,titanium plate gr7, which has brought unprecedented opportunities and challenges to medical material research units, material manufacturers, medical research institutions and clinical medical experts in China. These units should strengthen cooperation and work hard to achieve the localization of high-end implants for the benefit of the people. To promote the healthy and stable development of China's medical titanium alloy industry. Return to Sohu to see more Responsible Editor:. yunchtitanium.com
