Are unalloyed and considered commercially pure or “CP”. Generally the tensile and yield strength goes up with grade number for these “pure” grades of titanium. The difference in their physical properties is primarily due to the quantity of interstitial elements. They are used for corrosion resistance applications where cost and ease of fabrication and welding are important.
Is the most commonly used alloy. It has a chemical composition of about 6% Aluminium, 4% Vanadium and the remainder titanium. Grade 5 is used in Aerospace, Medical, Marine, and Chemical Processing.
Is commonly known as Ti6Al4V, Ti-6AL-4V or simply Ti 6-4. It is a purer, more precise composition
version of Grade 5. It contains exactly 6% high grade Aluminium, 4% pureVanadium and the remainder
in Grade 4 titanium. Grade 6-4 is used extensively inAerospace, Medical, Marine, and Chemical
Processing; in high load and hightemperature environments.
Contains 0.12 to 0.25% Palladium. This grade is similar to Grade 2. The small quantity of Palladium added
gives it enhanced crevice corrosion resistance at low temperatures and high pH.
Contains 3.0% Aluminium and 2.5% Vanadium. This grade is a compromise between the ease of welding and manufacturing of the “pure” grades and the high strength ofGrade 5.
It is commonly used in aircraft tubing for hydraulics or in athletic equipment.
Contains 0.3% Molybdenum and 0.8% Nickel.
Contains 3% Aluminium, 8% Vanadium, 6% Chromium, 4% Zirconium, and 4%Molybdenum. Also know as Beta C – 19
Contains 6% Aluminium, 4% Vanadium.It is called Gr5ELI or Ti6Al4V ELI for medical use.
Contains 4% Aluminium, 2.5% Vanadium, and 1.5% Iron. This grade was developed in the 1990s for use as an armour plating. The iron reduces the amount of Vanadium needed for corrosion resistance. Its mechanical properties are very similar to Grade 5.
