Original Title: Grade 9 Yield Strength Hardness Gr9 Titanium Alloy Composition Grade 9 Abbreviated Gr9 or Gr.9 Grade 9 titanium alloy is an advanced alpha titanium alloy with a nominal composition of Ti-3Al-2.5V,titanium tubing price, which has been developed for use in cold-workable tubing applications. Its strength is 20% -50% higher than that of pure titanium at room temperature and high temperature,nickel titanium wire, and its weldability and cold formability are superior to those of TC4 alloy. The maximum operating temperature is about 315 ℃. Due to its lower Al- and V content, titanium seamless tube ,6al4v titanium bar, the alloy is also known as "Half 6-4". It is almost impossible to improve its strength by targeted heat treatment (age hardening). Its already excellent corrosion resistance can be further improved by small additions of Pd (0.05%) or Ru (0.1%). Although the strength of this alloy is not as high as that of TC4 alloy, it has been widely used because of its excellent cold workability. Grade 9 titanium alloy seamless pipe is suitable for aircraft and engine hydraulic and fuel pipeline systems, and has been used in various military and civil aircraft and aerospace applications. The alloy can also be rolled into foil and strip, the former is mostly used in aircraft honeycomb structure. Mechanical properties Density: 4.47 G/cm, The room temperature elastic modulus is 118-123 GPa, Phase transformation point: 925 ℃, Hardness 15 ~ 17HRC.
