Titanium 6Al-4V alloy is an alpha + beta alloy, containing 6% aluminum and 4% vanadium. It is designed for a good balance of characteristics, including strength, ductility, fracture toughness, high-temperature service, creep resistance, weldability, workability and thermal processing (higher strength is easily obtained through treatment).
Ti 6-4 is, therefore, used for many airframe and engine parts and is commonly referred to as the "workhorse" of Titanium alloys, accounting for as much as 50% of the world's total Titanium usage. There are a great many applications for Titanium 6Al-4V in aircraft, where high reliability is required. General structural materials such as bolts and seat rails are made from Ti 6-4. In engines, the alloy is used for fan blades and cases in the intake section where temperatures are relatively low.
Its usability lies in its many benefits. Ti 6Al-4V may be heat-treated to increase its strength. It can be used in welded construction at service temperatures of up to 600° F. Titanium 6Al-4V alloy offers its high strength at a lightweight, useful affordability, and high corrosion resistance. This makes it an ideal choice for use across may platforms including aerospace, medical, marine and chemical processing industries.

Ti 6Al 4V alloy is widely heat-treated to further improve its properties. It is typically mill annealed, solution treated or aged. Stress relieving is used on formed and welded parts whilst beta annealing is used to improve the alloy's strength.
Ti 6Al 4V instantaneously produces a ceramic oxide layer on its surface, which protects it from carrion in all but the most severe of environments. Because of this, grade 5 Titanium is widely used in salt water applications, as well as humid environments. It is also moderately resistant to highly acid environments though titanium alloys containing palladium are better.
Ti 6Al 4V is usually hot worked in order to produce the desired microstructure through the process of recrystallisation. This keeps the alloys yield strength and hardness low and its ductility high. In grade 5 this is done at approximately 870°C to 980° C which stops the growth of excessive alpha phase.
Ti 6AL 4V is not easily cold worked due to its low elastic modulus meaning it has a tendency to resume its prior shape. Grade 5 can be cold drawn and extruded though this is typically confined to smaller industrial processing facilities on commercially pure grades of titanium.
Ti 6Al-4V can be welded using Ti 6Al-4V as a filler metal. The metal has to be shielded with inert gases to prevent the pickup of oxygen in the weld area which can cause embrittlement and failure. Gas tungsten arc welding is the most commonly used welding process for Ti 6Al-4V alloy, though gas metal arc welding is used for welding thicker sections.
Ti 6Al-4V can be successfully welded using plasma arc welding, spot welding, electron beam, laser beam, resistance welding and diffusion welding.
Ti6Al4V parts have good machinability and can be machined as stock parts. The following factors contribute to efficient machining of Ti6Al4V parts: Low cutting speeds, high feed rate, generous quantities of cutting fluid, sharp tools and a rigid setup. You can learn more on our machining page.
