Common Processing Standards And Technical Requirements For TC4 Titanium Rods

Titanium is a metal element, gray, atomic number 22, relative atomic mass 47.867. can burn in nitrogen, high melting point. Dull titanium and titanium-based alloys are new structural materials, mainly used in the aerospace industry and marine industry. Because titanium has a high melting point, small specific gravity, high specific strength, good toughness, fatigue resistance, acid and alkali corrosion resistance, low thermal conductivity, high and low temperature resistance, good performance, in the rapid cold and heat conditions of the stress is small, etc., its commercial value in the 1950s began to be recognized by the people, is used in aviation, aerospace and other high-tech fields. And it has been continuously promoted to the industries of chemical industry, petroleum, electric power, seawater desalination, construction and daily necessities.
