The grades of titanium vary depending on the metal alloy. Titanium grades show how much resistance the metal has in relation to the strength. Although titanium is durable in its purest form, once it’s combined with other elements it becomes stronger – these are known as titanium alloys.
Grades of Titanium
Grade 1 (commercially pure titanium) is titanium in its purest form. Compared to grade 5 titanium, grade 1 has less ductility to offer.
Grade 5 titanium is the one which is used most of all alloys. Titanium grade 5 has an exceedingly high strength making it more reliable under extreme conditions. This type of titanium is normally associated with aerospace and marine industries because it can withstand temperatures up to 600°F.
Titanium grade 12 has greater resistance against heat which makes it particularly useful for tube heat exchangers. This type of titanium is perfect for welding because it offers high-strength stability.
Titanium Grade 1-4 is pure Titanium, the other grades are alloys. When combined with two or more metals, Titanium is known as an alpha-beta alloy.
While beta Titanium alloys can offer improved strength and durability, pure Titanium is often used due to its high corrosion resistance, with the alloys being reserved for when strength–to–weight ratio is paramount.
- Grade 1 – Pure Titanium, relatively low strength and high ductility. Used in Plate heat exchangers
- Grade 2 – The pure titanium most used, Titanium Grade 2 is the best combination of strength, ductility and weldability. Ideal for piping systems.
- Grade 3 – High strength Titanium, used for Matrix-plates in shell and tube heat exchangers.
- Grade 5 – (Ti-6Al-4V – alpha-beta alloys)The most common titanium alloys. Exceedingly high strength. High heat resistance. Used in the Aerospace industry, and subsea applications.
- Grade 7 – Enhanced corrosion resistance in reducing and oxidising environments. Used in the chemical industry.u
- Grade 9 – Very high strength and corrosion resistance. Used in hydraulic piping, and subsea.
- Grade 11 – Applications as for Grade 7. Suitable for deep drawing.
- Grade 12 – Better heat resistance than pure Titanium. Applications for Grades 7 and 11. Shell and tube heat exchangers
Grades Of Titanium FAQs
The titanium grade you need is dependent on the project you’re doing, as each has different benefits.
All grades of titanium are incredibly strong and resistant to corrosion, meaning they can still perform under the harshest of conditions.
The higher grades of titanium (5-12) are alloys created with specific benefits in mind. Grade 12 for example, has excellent heat resistance, making it the perfect choice for shell and tube heat exchangers, hydraulic piping and equipment in the chemical industry.
Grades 1-4 are pure titanium and are perfect if you need a weldable, ductible material for piping systems and tubing. You’ll find lower grades of titanium being used in marine and industrial industries.
If you’re starting a project and aren’t confident in which grade of titanium would be the best option for you, don’t hesitate to get in touch with us today; we’re more than happy to help.
At Ti-Tek, we have a selection of titanium grades available, ranging from grade one to grade twelve.
Titanium grades 1-4 are pure titanium, while the higher grades are alloys.
The alloy grades are popular due to their high strength-to-weight ratio.
We find that the most commonly used titanium grade is five. While still having a high percentage of titanium, this grade is one of the most reliable forms, as it can withstand temperatures of up to 600°F and can endure extreme conditions.
Higher grades of titanium are favoured by industries such as aerospace and marine industries due to their hard-wearing qualities and resistance to corrosion.
Conversely, the lower grades are mostly used for welding due to their lower strength.
