Ti-6-4, UNS R56400, ASTM grade 5 titanium, Ti6Al4V

Its chemical composition is 6% aluminum, 4% vanadium, 0.25% (max) iron, 0.2% (max) oxygen, and the balance is titanium.

It is significantly stronger than commercially pure titanium (grades 1-4) while having the same stiffness and thermal properties (excluding thermal conductivity, grade 5 titanium has approximately 60% lower thermal conductivity than CP titanium)

It has many advantages, one of which is that it is heat treatable. This grade offers an excellent combination of strength, corrosion resistance, weldability and processability.

This alpha-beta alloy is the workhorse alloy of the titanium industry. The alloy is fully heat-treatable in cross-sections up to 15 mm and can be used at temperatures up to approximately 400°C (750°F). As it is the most commonly used alloy - over 70% of fused gold grades are sub-grades of Ti6Al4V, its uses cover many aerospace airframe and engine component uses, as well as major non-aerospace applications in marine, offshore and power generation, particularly It's an industry.

The addition of 0.05% Palladium (Grade 24), 0.1% Ruthenium (Grade 29) and 0.05% Palladium and 0.5% Nickel (Grade 25) significantly improves corrosion resistance in reduced acids, chlorides and acidic environments, thereby improving attack temperatures exceeding 200°C (392°F).
