Titanium Product Guide
Much like other metals in the materials industry, Titanium has many different grades. Grade 2 being the most commonly used in pure titanium and Grade 5 (6AL-4V) is the most commonly used for alloy titanium, both being considered the “Workhorse” in the titanium world. Titanium is widely used because it’s high corrosion resistance and high strength to weight ratio. Typical applications are; aerospace, automotive, medical, industrial, chemical, petroleum and other common industries.
Grade 1
Grade 1 titanium is a relatively low strength with high ductility. It is the softest and most ductile of the various grades of titanium. Because of these qualities, Grade 1 is commonly used for it’s formability.
Common Applications:
- Chemical Processing
- Architecture
- Medical
- Marine
- Automovtive
- Air Craft
| Grade 1 Titanium | ||
|---|---|---|
| Minimum Properties | Ultimate Tensile Strength, psi | 34800 |
| Yield Strength, psi | 24700-45000 | |
| Brinell Hardness | 120 | |
| Rockwell B Hardness | 70 | |
| Chemistry | C | Max .1 |
| Fe | Max .2 | |
| H | Max .015 | |
| N | Max .03 | |
| O | Max .18 | |
| Ti | 99.5 |
Grade 2
Grade 2 Titanium has the best combination of strength, ductility and weld-ability. Commonly known as the “workhorse” in the titanium industry, Grade 2 is more useable and available.
Common Applications:
- Architecture
- Medical
- Marine
- Exhaust
- Air Craft
- Chemical
- Automotive
| Grade 2 Titanium | ||

| N | Max .03 | |
| O | Max .25 | |
| Ti | 99.2 |
Grade 3
Grade 3 titanium is one of the least used grades of commercially pure titanium. Grade 3 is stronger than both grade 1 and 2, but similar in ductility and less formability. Grade 3 has a higher mechanical properties allowing for greater use in applications needing moderate strength and higher corrosion resistance.
Common Applications:
- Aerospace
- Chemical
- Medical
- Marine

| N | Max .05 | |
| O | Max .35 | |
| Ti | 99.1 |
Grade 4
Grade 4 Titanium is well known for its high strength, corrosion resistance and good formability. Grade 4 is also most widely used in the medical industry.
Common Applications:
- Medical
- Cryogenic
- Surgical Equipment
- Heat Exchange
| Grade 4 Titanium | ||
|---|---|---|
| Minimum Properties | Ultimate Tensile Strength, psi | 95700 |

| O | Max .4 | |
| Ti | 99 |
Grade 5 (6AL-4V)
Grade 5, also known as 6AL-4V, is considered the “workhorse” for the alloy titanium. Most commonly used because of its high strength to weight ratio and its corrosion resistance. Grade 5 can also be heat treated to increase the strength.
Common Applications:
- Aerospace
- Automotive
- High-performance
- Marine
- Sports equipment
