Grade 2 Titanium vs 6061-T6 Aluminium – What’s the Difference?

Titanium and Aluminium are widely used in various industries, from aerospace to medical devices. Both have unique properties and strengths that make them suitable for different applications. One of the most common types of titanium is Grade 2, while 6061-T6 Aluminium is widely used in the manufacturing industry. This blog post will discuss the differences and similarities between Grade 2 titanium and 6061-T6 Aluminium, including their properties, uses, and pros and cons.

Difference between Grade 2 Titanium and 6061-T6 Aluminium


Grade 2 titanium is pure titanium with a light silver colour and an excellent strength-to-weight ratio. It is highly resistant to corrosion, fatigue, and wear, making it ideal for use in environments with high temperatures and harsh chemicals. On the other hand, 6061-T6 Aluminium is an alloy that comprises Aluminium, magnesium, and silicon. It has a good strength-to-weight ratio, excellent heat resistance, and easy machinability. However, it is less corrosion-resistant than titanium, making it unsuitable for certain applications.


Grade 2 titanium is commonly used in aerospace, medical implants, marine equipment, and chemical processing plants due to its excellent corrosion resistance and biocompatibility. It is also used in sporting goods, jewellery, and other consumer products. 6061-T6 Aluminium is used in the manufacturing industry, particularly in the aerospace and automotive sectors, due to its high strength, durability, and ease of machining. It is also commonly used in bicycle frames, boat building, and construction.

Pros and cons:

Grade 2 titanium is expensive, but its excellent strength and corrosion resistance make it a valuable investment for long-term use. It is also biocompatible, making it safe for medical implants and prosthetics. However, it isn’t easy to manufacture and requires specialized expertise. 6061-T6 Aluminium, on the other hand, is more affordable and easier to manufacture, making it a popular choice for mass-produced products. It also has good strength and durability but is less corrosion-resistant than titanium, making it unsuitable for certain applications.


Grade 2 titanium is difficult to machine due to its high strength and hardness compared to other materials such as Aluminium. It requires specialized tools and expertise to work effectively. 6061-T6 Aluminium, on the other hand, is relatively easy to machine due to its lower strength and good machinability. It can also be welded and fabricated into various shapes and sizes, making it highly versatile.


As mentioned earlier, Grade 2 titanium is expensive due to its high strength, corrosion resistance, and biocompatibility. Depending on the application and quantity required, it can cost up to ten times more than 6061-T6 Aluminium. This cost factor makes titanium less accessible and more suitable for high-end applications, while Aluminium is more cost-effective and versatile. For more information visit MarketsMartb2b


Grade 2 titanium and 6061-T6 aluminium have unique properties, strengths, and weaknesses. While titanium is more corrosion-resistant and biocompatible, it is also more costly and difficult to machine than Aluminium. On the other hand, Aluminium is more affordable, easier to manufacture, and versatile but may not be suitable for applications that require high corrosion resistance, such as medical implants. Choosing these materials depends on the specific application, budget, and performance requirements.
