Titanium Alloy Knowledge

Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high specific strength, good corrosion resistance and heat resistance. Many countries in the world have recognised the importance of titanium alloy materials, and have successively conducted research and development on them and obtained practical applications. Titanium is the periodic table Ⅳ B class elements, the appearance of steel, melting point of 1,672 ℃, is a refractory metal. Titanium in the earth's crust is rich, much higher than Cu, Zn, Sn, Pb and other common metals. China's titanium resources are extremely rich, only found in Sichuan Panzhihua area of very large vanadium and titanium magnetite, associated titanium metal reserves of about 420 million tonnes, close to the sum of foreign proven titanium reserves. Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium - molybdenum, titanium - palladium alloys, etc.), low-temperature alloys, as well as special functional alloys (titanium - iron hydrogen storage materials and titanium - nickel memory alloys) and so on.
