Titanium is less than 57% of iron, but it has the characteristics of high strength, high temperature resistance and corrosion resistance. It is called “marine metal” and “space metal” and so on. It is an important and supporting material for advanced national defense equipment and important projects of national economy. On April 15, the 17th National Symposium on Titanium and Titanium Alloys was opened in Ningxia, sponsored by China Nonferrous Metals Society and sponsored by Nanjing University of Technology.

With the theme of “innovation, development and application”, this conference has conducted extensive and in-depth exchanges and discussions on the latest development, research hotspots and development priorities of titanium science and technology in recent years in China, attracting more than 70 units from China Nonferrous Metals Society, Nanjing University of Technology, Baoti Group, Northwest Nonferrous Metals Academy and China Shipbuilding Heavy Industry Group to engage in titanium and titanium. Six academicians and more than 530 experts and scholars have studied alloy metallurgy, materials, manufacturing, aerospace, marine engineering, petrochemical, biomedical and other related application fields.

“In recent years, titanium alloys and industry in China have made great progress. They have been widely used in chemical industry, aviation, aerospace, warships, nuclear power, biomedical and other fields. They are key materials for improving equipment performance, important supporting materials for modern national defense construction and indispensable important materials for national economic development.” Academician Zhou Lian, part-time professor and honorary chairman of the conference of Nanjing University of Technology, said that even in the field of daily necessities, titanium is often seen, including high-end cooking utensils, mobile phones, luxury goods and so on.

“In 2018, the output of titanium alloy in China was 60,000 tons, accounting for 0.006% of steel, but the price was 16.9 times that of steel. Low yield and high unit price are serious problems in the application of titanium and titanium alloys. Professor Chang Hui, Vice-Dean of Material College of Nanjing University of Technology, believes that reducing the cost of titanium alloy materials by more than 50%, increasing the utilization rate of titanium alloy materials to more than 90%, increasing the amount of titanium alloy by 5-10 times, reaching 300-600,000 tons/year is the goal of the next 5-10 years.
