Grade 5 Titanium: 6AL-4V Titanium, UNS R56401, AMS 4928

Grade 5 alpha-beta alloy titanium is the most commonly used alloy in many different industries. Grade 5 is also labeled 6AL-4V, and at Titanium Processing Center we are a fully stocked distributor and can ship the titanium you need, when you need it. The titanium TI-6AL-4v alloy is a lot stronger than commercially pure titanium, but still has the same stiffness and most of the same thermal properties (it is much lower in Grade 5 than other alloys).

One of the most important characteristics of 6AL-4V titanium, though, is that it is heat treatable and most can even be welded. Whether you are in the aerospace, automotive, or other industries, this alloy can be used in a wide range of applications. The chart shows the mechanical, tensile, and physical properties of this grade 5 alloy titanium.  Some of our available products include 6AL-4V titanium sheet, bar, extrusions, strip, wire as well as custom-made products.
