The density of titanium is less than about 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". It is an important part of national defense advanced equipment and important projects of national economy. Support material. On April 15th, the 17th National Titanium and Titanium Alloy Academic Exchange Conference hosted by the China Nonferrous Metals Society and Nanjing University of Technology was opened in Ning.
With the theme of “Innovation, Development and Application”, this conference has extensive and in-depth exchanges and discussions on the latest developments, research hotspots and development priorities of titanium science and technology in recent years, attracting from the China Nonferrous Metals Society and Nanjing. More than 70 units including Industrial University, Baoti Group, Northwest Nonferrous Metals Institute, China Shipbuilding Industry Group, etc., engaged in titanium and titanium alloy metallurgy, materials, manufacturing, and aerospace, marine engineering, petrochemical, biomedical and other related applications. 6 academicians and more than 530 experts and scholars.
"In recent years, China's titanium alloys and industries have been greatly developed and have been widely used in chemical, aerospace, aerospace, shipbuilding, nuclear power, biomedical and other fields. It is a key material for improving equipment performance and an important supporting material for modern national defense construction. And important materials that are indispensable for the development of the national economy.” Academician Zhou Lian, an adjunct professor and chairman of the conference at Nanjing University of Technology, said that even in the daily necessities, titanium is often seen, including high-end cookware, mobile phones, and luxury goods.
“In 2018, China’s titanium alloy production was 60,000 tons, accounting for 0.006% of steel, but the price was 16.9 times that of steel. Low output and high unit price are serious problems for titanium and titanium alloy applications.” School of Materials, Nanjing University of Technology Professor Chang Hui, the vice president, believes that the manufacturing cost of titanium alloy materials is reduced by more than 50%, the utilization rate of titanium alloy materials is increased to over 90%, and the amount of titanium alloy is increased by 5-10 times, reaching 300,000-600,000 tons/year. The goal of the next 5-10 years.
