What is a Titanium Rod?
Alpha alloys contain a certain amount of elements that stabilize the alpha phase, and are mainly composed of the alpha phase in equilibrium. Alpha alloy has a small specific gravity, good thermal strength, good weldability and excellent corrosion resistance. The disadvantage is low room temperature strength, which is usually used as a heat-resistant material and corrosion-resistant material. Alpha alloys are generally divided into full alpha alloys (TA7), near alpha alloys (Ti-8Al-1Mo-1V), and alpha alloys (Ti-2.5Cu) with a small amount of compounds.

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 high heat resistance. Many countries in the world have realized the importance of titanium alloy materials, researched and developed them successively, and obtained practical applications. Titanium is a group IVB element in the periodic table. It looks like steel and has a melting point of 1 672 . It is a refractory metal. Titanium is abundant in the earth's crust, much higher than common metals such as Cu, Zn, Sn, and Pb. China's titanium resources are extremely rich. Only the extra large vanadium-titanium magnetite found in the Panzhihua area of Sichuan has an associated titanium metal reserve of approximately 420 million tons, which is close to the total 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, and special-function alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys), etc. .
Seventeen projects, including titanium rods and wires in Baoji Industrial Park, with a total investment of 3 billion yuan, represent the latest technology and equipment level of the titanium industry today. [1]
