What is the best grade of titanium?

Whether you’re looking for titanium metal to create components for vehicles, aircraft or sports equipment, you’re sure to find what you need at Ti-Tek.

Our team has the skill and expertise to cut metal to the exact size and supply a wide range of titanium rods, and other products, in several alloys and grades. But what’s the best grade?

What is the best grade of titanium?

Take a look at the different titanium grades available below, and discover more about their uses and benefits:

Titanium Grade 1

The first of four – titanium grade 1 is the softest, most ductile commercially pure grade. Offering high impact toughness and resistance, it’s the perfect choice for applications where formability is required.

Titanium grade 1 tubes and plates are suitable for:

  • automotive parts
  • airframe structures
  • dimensionally stable anodes

Titanium Grade 2

Titanium grade 2 is unalloyed titanium, commonly known as Titanium Beta-C. It’s considered to be ‘commercially pure’, is lightweight and offers excellent resistance to corrosion.

Grade 2 has strong weldability properties, making it an excellent choice for applications that require welding. Other applications include:

  • architecture
  • desalination
  • exhaust pipe shrouds/heat shield
  • power generation

Here at Ti-Tek, we produce a selection of titanium rods and machined components in grade 2.

Titanium Grade 3

Although less common than the other three commercially pure metals, titanium grade 3 is no less important. It provides similar ductility and formability as grades 1, 2 and 4, but higher mechanical properties.

Grade 3 is ideal for:

  • aerospace
  • chlorate manufacturing
  • hydro-carbon processing
  • marine

Titanium Grade 4

Out of all four grades of commercially pure titanium (grades 1-4), titanium grade 4 provides the most strength. One of the biggest benefits of this grade is that it offers a low level of ductility and can be cold formed.

Its qualities mean titanium grade 4 can be used in a range of environments but is mostly used in:

  • aerospace
  • chemical processing
  • industrial

Grade 4 is formed into bars, sheets and wires and has recently found a niche within the medical industry to produce surgical hardware.

Titanium Grade 5

The most commercially available titanium-based alloy, worldwide. Titanium grade 5 is an alpha-beta alloy, renowned for its high strength and toughness, and alloyed with 6% aluminium and 4% vanadium. It can also be referred to as Ti 6Al-4V or the ‘workhorse’ of alloys.

The characteristics of titanium grade 5 such as good weldability and fabrication, make it ideal for:

  • aerospace
  • chemical processing
  • marine
  • medical

We stock titanium rods and bars in Ti6Al-4V, so be sure to contact us if you’d like to know more.

Titanium Grade 7

In terms of mechanical and physical properties, titanium grade 7 is like grade 2 – only it features palladium, an impurity found in ‘pure metals’ which makes it an alloy.

Guaranteeing great weldability, fabrication, resistance to corrosion and helping to reduce acids, titanium grade 7 is perfect for:

  • chemical processing
  • desalination
  • power generation

It can be easily formed into bars, plates, sheets, tubes, wires and rods.

Titanium Grade 9

Titanium grade 9, sometimes referred to as Ti 3Al-2.5V, is made from titanium with 3% aluminium and 2.5% vanadium. The strength of titanium grade 9 falls between that of grade 4 and 5 but is more formable and weldable. It also weighs 60% less than steel and has good cold rolling properties.

Great for tubing, pipes and vessels, titanium grade 9 is typically used for:

  • aerospace
  • automotive
  • offshore oil and gas

Titanium Grade 11

Titanium grade 11 is most like grade 1 but with a little palladium for extra corrosion resistance. The palladium provides protection against crevice erosion and reduces acid in chloride environments and comes in useful for:

  • chemical processing
  • chlorate manufacturing
  • marine

This grade is usually formed into titanium rods or tubes.

Titanium Grade 12

Renowned for its quality weldability, Titanium grade 12 provides a lot of strength at high temperatures and possesses similar characteristics to 300 series stainless steel.

When it comes to forming titanium grade 12, there are several options – be it press brake, hydropress, stretch or drop hammer – making it ideal for many different applications, including:

  • shell and heat exchangers
  • chemical manufacturing
  • marine
