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

Titanium and aluminium are two metals that are widely used in manufacturing industries. While

they may be similar in terms of appearance and structural composition, but there are distinct

differences between them that need to be understood, especially regarding their grades.

In this blog post, we will discuss the differences between Grade 2 Titanium and 6061

Aluminium is the most commonly used grade of each metal.

Difference between Grade 2 Titanium vs. 6061 Aluminium


Grade 2 Titanium is a commercially pure titanium alloy commonly known for its high

strength-to-weight ratio, excellent fatigue, and corrosion resistance. It is used in

medical implants, aerospace components, and sporting equipment. Titanium is also lightweight

and biocompatible, and its non-toxic nature makes it perfect for use in non-implant and

implant medical instruments.

Fabrication of aircraft 

On the other hand, 6061 Aluminium is an alloy mainly made of aluminium, magnesium, and

silicon. Like Grade 2 Titanium, it is widely used in various manufacturing industries due to its

high strength-to-weight ratio, good corrosion resistance, and machinability. 6061 Aluminium is

commonly used in the fabrication of aircraft and state-of-the-art bicycles. However, it could be a

more suitable material for medical applications due to its toxicity and reactive nature.

Mechanical properties

The primary difference between the two materials is the way they are graded. Titanium grades

are classified according to their mechanical properties: Grades 1-4 are considered commercially

pure, with Grade 2 offering the most excellent balance of strength and flexibility. The 6061

Aluminium alloy, on the other hand, is classified according to its chemical composition, with

Grade 6061 is the most commonly used due to its flexibility and ease of welding.

Corrosion resistance

Another difference lies in how these materials are machined. Grade 2 Titanium is a material

that’s challenging to machine but is a favourite in the aerospace industry due to its excellent

strength and corrosion resistance. 6061 Aluminium, however, is straightforward to machine due

to its chemical composition, allowing it to be fabricated efficiently into a range of shapes and


Moreover, manufacturing with Grade 2 Titanium requires high expertise and skill due

to its toughness and rigidity, as it tends to snap rather than bend. In contrast, 6061 Aluminium is

much more malleable and can be easily formed and fabricated. For more information visit MarketsMartb2b


In summary, understanding the differences between Grade 2 Titanium and 6061 Aluminium is

essential for anyone looking to work with these materials. While both offer a high

strength-to-weight ratio, corrosion resistance, and durability, there are significant differences in

how they’re graded, machined, and fabricated. Ultimately, the choice of metal will depend on the

intended application and the specific properties you want in a material. So, 

choosing the right metal grade for aerospace components, medical implants, or state-of-the-art bicycles is crucial to ensure optimal performance and durability.
