Grade 5 vs Grade 6 Titanium – What’s the Difference?

Titanium is a popular metal that is used for various applications. From aerospace to medical implants, titanium has become a go-to material. However, titanium has different grades that offer different mechanical properties. Two popular grades of titanium are grade 5 and grade 6. Titanium Grade 5 and Grade 6 are similar, but they have some differences. This blog post will discuss the difference between Grade 5 and Grade 6 titanium.

Difference Between Grade 5 and Grade 6 Titanium

Chemical Composition

One of the main differences between Grade 5 and Grade 6 titanium is their chemical composition. Grade 5 titanium is alloyed with 6% Aluminum and 4% Vanadium, while Grade 6 titanium is alloyed with 6% Aluminum, 2% Zirconium, and 2% Tin. This difference in composition can affect the mechanical properties of the two grades differently.


Grade 5 titanium is stronger than Grade 6 titanium. The addition of Vanadium in Grade 5 titanium reinforces the metal’s crystalline structure and enhances its strength. Moreover, Grade 5 titanium has high tensile strength and fatigue resistance, which makes it ideal for applications that require high load-carrying capacity. On the other hand, Grade 6 titanium has lower strength but higher flexibility, making it easier to form into shapes.

Corrosion Resistance

Both Grade 5 and Grade 6 titanium show excellent corrosion resistance. However, Grade 5 titanium holds up better in corrosive environments, such as seawater. Adding Vanadium increases the resistance to corrosive environments in Grade 5 titanium. This makes it a popular choice for marine applications where corrosion is a concern.


Grade 5 titanium is more difficult to weld than Grade 6 titanium. The high strength properties of Grade 5 titanium make it challenging to weld, and specific welding techniques are required. On the other hand, Grade 6 titanium has better weldability due to its lower strength and high flexibility.


Grade 5 titanium is commonly used in high-performance applications that require consistent strength, high load-carrying capacity, and excellent corrosion resistance. Some of the applications of Grade 5 titanium include aerospace components, surgical instruments, racing components, and sporting goods. Grade 6 titanium, on the other hand, is preferred for applications that require excellent formability and weldability, such as tubing, heat exchangers, and marine hardware.

In conclusion, we can say that while Grade 5 and Grade 6 titanium are used for a wide range of applications, they have different properties that make them suitable for specific needs. Grade 5 titanium is stronger and shows better corrosion resistance, while Grade 6 titanium has better formability and weldability. Understanding the differences between the two grades is essential before choosing the right material for your application. Always consult experts before making a decision, and never compromise on quality.
