All You Need to Know About Titanium Alloys

titanium alloys grades

Titanium alloys are a popular choice for many industrial applications due to their strength, lightweight, and corrosion resistance. They can be used in everything from aerospace components to medical implants. But what exactly is a titanium alloy, and what different types are available? Let’s take a look.

Titanium alloys are created when two or more elements are combined with titanium to enhance their properties. Commonly added elements include aluminum, tin, vanadium, molybdenum, and zirconium. The combination of these elements creates a variety of different titanium alloys that can be used for various applications, depending on the desired properties.

Types of Titanium Alloy

Ti 6AL 4V (or Grade 5)

The most common type of titanium alloy is called 6AL-4V (or alloy Grade 5), which is composed of 6% aluminum and 4% vanadium. This alloy offers excellent strength and durability while still being relatively lightweight. It is often used in the aerospace industry due to its high strength-to-weight ratio and resistance to corrosion. Additionally, it has good weldability and can withstand extreme temperatures without becoming brittle or losing its shape.

Ti 6al 2sn 4zr 2mo(or Grade 9)

Another popular type of titanium alloy is 6al 2sn 4zr 2mo (or Grade 9). This alloy contains 2% aluminum, 2% tin, 4% zirconium, and 2% molybdenum in addition to the base titanium element. It boasts even higher levels of strength than 6AL-4V while still maintaining good ductility at low temperatures, making it an ideal choice for cryogenic applications such as liquid natural gas tanks or cryogenic tanks on rockets/spacecraft. It also has excellent fatigue resistance at elevated temperatures and superior corrosion properties compared to other alloys. Moreover, it can be cold-worked much more easily than 6AL-4V for greater design flexibility.


Titanium alloys are incredibly strong yet lightweight materials that offer excellent corrosion resistance and weldability, making them ideal for use in a wide range of industries, from aerospace engineering to medical implants. The two most common types of titanium alloys are 6AL-4V (Grade 5) and Ti-6AL-2Sn-4Zr-2Mo (Grade 9 alloy). Each has its own unique set of properties that makes it best suited for specific applications, so it’s important to choose the right one for your needs! Whether you’re looking for increased strength or better cryogenic performance, there’s sure to be a titanium alloy that meets your requirements perfectly!
