Grade 5 vs Grade 4 Titanium – What’s the Difference?

Titanium is a popular choice when selecting the right metal for your next project. Known for its incredible strength, corrosion resistance, and lightweight nature, it’s no wonder titanium has become a go-to material for countless industries. However, not all titanium is created equal. In this blog post, we’ll explore the key differences between Grade 5 and Grade 4 titanium, two of the most commonly used grades of titanium, to help you better understand which is best for your specific needs.

Difference between Grade 5 vs Grade 4 Titanium


First, let’s start with exactly Grade 5 and Grade 4 titanium. Grade 5 (Ti 6Al-4V) is a titanium alloy comprising 6% aluminium and 4% vanadium. It’s the most commonly used titanium alloy known for its strength, durability, and corrosion resistance. Grade 4 (Ti-4AI-3V) is a slightly older version of titanium-containing 4% aluminium and 3% vanadium. It’s also known for its strength and durability but is slightly less corrosion-resistant than Grade 5.

Chemical compositions

The key differences between the two grades of titanium can be seen in their chemical compositions and resulting properties. Grade 5 titanium has a higher tensile strength and fatigue strength than Grade 4 titanium, making it stronger and more resistant to tear and wear. Grade 5 titanium has a lower thermal conductivity than Grade 4 titanium, making it better suited for high-temperature applications. On the other hand, Grade 4 titanium is easier to process due to its lower oxygen content, making it a popular choice for welding and brazing projects.


Regarding cost, Grade 5 titanium is generally more expensive than Grade 4 titanium due to its higher strength and corrosion resistance. The cost difference can be significant, particularly for larger projects, so it’s important to consider both the upfront cost and long-term benefits of each type of titanium.


Another important factor to consider when choosing between Grade 5 and Grade 4 titanium is the specific application or project that you’re working on. If you’re looking for a material that can withstand extreme temperatures, humidity, and saltwater exposure, Grade 5 titanium is likely your best bet. However, if you’re looking for a less expensive option that’s easier to machine and weld, Grade 4 titanium may be better. For more information visit MarketsMartb2b


Ultimately, the decision between Grade 5 and Grade 4 titanium comes down to your project’s specific needs and requirements. While both grades of titanium offer incredible strength and durability, they have different properties that make them better suited for certain applications. By understanding these differences and weighing the pros and cons of each option, you can make an informed decision that will help your project succeed.
