Ti 6Al-4V (Grade 5)

Introduction

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.
