What Grade of Titanium Do I Need?

Quite frequently, we’re asked what the best grade of titanium would be for someone’s application. This is more often true for hobbyists or those new to the use of titanium. While we can’t recommend the best grade for your application, we can provide data sheets to help point you in the right direction. We suggest talking to the manufacturer’s engineering or metallurgy departments to be sure you are ordering the right material for your parts.

Some things to think about when choosing a grade:

  • What is the end use of my product? Different grades are more common for different industries and end uses. For example, the properties of 6AL-4V ELI may make it suitable for medical and dental applications. 6AL-4V, or Grade 5, is a very common grade for aerospace applications. For some applications, such as tooling or hobbies, machinists simply want an affordable option, such as Grade 2. But needs vary, and the most common or inexpensive grade is not necessarily the best one for your application.
  • Do I need the material to be weldable? Different grades have different levels of weldability, and some grades are not recommended to be welded at all.
  • What material specs or properties does my end product require? In the end, if requirements are imposed, you may not have any choice. You may be restricted to a certain grade. Different specifications, mechanical property requirements, and chemical makeup requirements will narrow down your choices.

Below are some common grades that we offer here at PTG. You can download our data sheets below for basic information regarding some of the questions above. For more extensive information, we recommend you get in touch with the manufacturer of the material. You can always contact us at 888.772.8984 or for assistance in reaching potential manufacturers.
