Products Description
The answer to what is 3AL 2.5 V titanium tubing is that this tubing is mainly used in aircraft applications, because it is in these applications that though the weight of the substance being used is critical, the substance also needs to have strength. Ti-3Al-2.5V has many useful properties due to which it is used in hydraulic systems. Cold working can be done of Ti-3Al-2.5V titanium tubing. Ti-3Al-2.5V tubing has been developed for fuel systems and hydraulic systems of aircraft. Ti-3Al-2.5V titanium tubing is also used in spacecraft and high technology military aircraft.
3AL 2.5 V Seamless titanium tubing weight by percentage is Titanium 90%, Aluminum 6%, Carbon < 0.10%, Nitrogen < 0.05%, Hydrogen < 0.0125%, Vanadium 4%, Oxygen < 0.20% and Iron < 0.3%. Seamless titanium tubes are used in many industries and applications like pulp and paper industry, marine industry, nuclear industry, sporting goods, petrochemical industry, chemical industry, medical industry, etc.
Titanium Grade 9 Tube (Titanium 3Al-2.5V) has been known for its high strength and toughness, durability and low density, and ability to withstand high and low temperatures. Ti-3Al-2.5V Tubing has medium strength that falls between Ti Grade 4 tubing and Ti Grade 5 tubing. It has excellent corrosion resistance and is used in Aerospace and Industrial applications. Ti-3Al-2.5V titanium tubing has Good Weldability & Cold Forming. Titanium Gr 9 Tube is an alpha alloy that is strengthened by cold working. Titanium Alloy Grade 9 Tube also exhibits good ductility and toughness. ASTM Specification are ASTM B861 Seamless Pipe & ASTM B862 Welded Pipe in Titanium grade 9 with ASTM/ASME specifications.
