About Ti 6Al-4V (Grade 5)

Ti 6Al-4V (Grade 5) is the most widely used of all the alpha-beta titanium alloys.The alloy was originally developed for the aerospace market and widely used in aerospace structural components. More recently the alloy has seen extensive use in the oil & gas market where a combination of high strength, corrosion resistance and low weight is essential.

The density of Ti 6Al-4V (Grade 5) is 50% that of nickel-based alloys and stainless steels. It is therefore used extensively in various applications due to its high strength-to-weight ratio.

It is typically used in the annealed condition, at service temperatures up to 400°C. However it may be heat treated for high strength in sections under 4″ thick.

Ti 6Al-4V (Grade 5) can be welded with matching or ELI filler wire.

  • Density: 4.429 g/cm³
  • Melting range: 1609 - 1660°C
  • Beta transus: 996 ± 28°C
