Grade 2 Titanium vs 6al4v – What’s the Difference?

Titanium is a versatile and corrosion-resistant metal commonly used for applications ranging from aerospace to medical implants. However, not all titanium grades are created equal. In this blog post, we’ll discuss two of the most popular titanium grades — grade 2 titanium and 6al4v titanium. We’ll also explore their differences and help you determine which is best for your particular needs.

Difference between Grade 2 Titanium and 6al4v


Grade 2 titanium is a pure titanium alloy comprising 99.2% titanium, making it one of the most ductile and formable. It is also called commercially pure-grade titanium. On the other hand, 6al4v titanium is an alloy made of 6% aluminium, 4% vanadium, and the remaining titanium. It is a lightweight alloy that is highly resistant to corrosion.


Although grade 2 titanium has a high level of ductility, it has the lowest strength of all titanium grades. It is ideal for applications that require formability and corrosion resistance rather than strength. On the other hand, 6al4v titanium is incredibly strong and has a higher strength-to-weight ratio than other titanium alloys. Hence, it is preferred for applications that require high strength, such as aerospace and medical implants.


The cost of titanium depends on various factors, such as grade, quantity, and size. Generally, the higher the titanium grade, the more expensive it is. Grade 2 titanium is less expensive than 6al4v titanium due to its lower strength and reduced alloys. However, when it comes to applications that require high strength, the added cost of 6al4v may be justified.


Grade 2 titanium is best suited for applications that require formability, such as architecture, jewellery, kitchenware, and marine applications. It is also used in the medical industry for bone pins, dental implants, and pacemaker cases. On the other hand, 6al4v titanium is preferred for applications that require high strength, including aerospace components, racing engines, and chemical processing equipment.


Weldability is an essential consideration for many applications as it affects the finished product’s structure, strength, and performance. Luckily, both grade 2 titanium and 6al4v titanium can be welded using different techniques such as TIG and MIG. 6al4v titanium requires more precaution while welding due to the presence of alloys like aluminium and vanadium, which can cause post-weld ageing.

Although grade 2 and 6al4v titanium are both titanium alloys, their composition, strength, cost, applications and weldability vary considerably. Therefore, before choosing which alloy best suits your needs, you should analyze the requirements for your specific application. Titanium is an outstanding metal with incredible corrosion resistance for various applications, and choosing the right grade will help you achieve better results.
