Titanium 6-4
6Al-4V Grade 5 Titanium
Material Data Sheet
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.
