Titanium
Titanium Product Guide
Titanium, much like other metals used in the manufacturing of products, is available in a wide variety of grades. Both Grade 2 (which refers to pure titanium) and Grade 5 (6AL-4V), which relates to alloy titanium, are referred to as the “Workhorse” in the titanium industry. Grade 2 is common for so many practical use. Titanium is used extensively as a result of its excellent corrosion resistance as well as its high strength-to-weight ratio. It is widely used in industrial, aircraft, chemical, automotive, medical, petroleum, and other sectors.

Grade 1
The titanium grade 1 has strong flexibility but only a somewhat low strength. The other grades of titanium are harder and less malleable than this one. It is the most malleable. And because it has these characteristics, Grade 1 is often utilized for its formability. It is widely used in:
- Marine
- Processing of Chemicals
- Air Craft
- Architecture
- Automotive
- Medical
| Grade 1 Titanium | ||
|---|---|---|
| Minimum Properties | Ultimate Tensile Strength, psi | 34800 |
| Yield Strength, psi | 24700-45000 | |
| Brinell Hardness | 120 | |
| Rockwell B Hardness | 70 | |

| Ti | 99.5 |
Grade 2
Grade 2 Titanium is the strongest, most flexible, and easiest to weld of all the grades. Grade 2, which is more usable and readily accessible, is referred to in the titanium industry as the “workhorse”. It is widely used in:
- Automotive
- Medical
- Chemical
- Exhaust
- Air Craft
- Marine
- Chemical
- Architecture
- Automotive

Grade 3
One of the least common grades of economically pure titanium is grade 3. The tensile strength of grade 3 is more than that of grade 1 and grade 2, although it is comparable in ductility and has less formability. And because of its superior mechanical capabilities, Grade 3 may be used to a larger extent in applications that call for medium quality and improved corrosion resistance. It is widely used in:
- Aerospace
- Medical
- Chemical
- Marine

| O | Max .35 | |
| Ti | 99.1 |
Grade 4
Grade 4 Titanium is a metal renowned for its great strength, excellent corrosion resistance, and superb formability. The medical industry makes the most extensive use of grade 4 for:
- Surgical Equipment
- Cryogenic
- Exchange of Heat
| Grade 4 Titanium | ||
|---|---|---|
| Minimum Properties | Ultimate Tensile Strength, psi | 95700 |

Grade 5 (6AL-4V)
Titanium alloy is referred to as the “workhorse” for the Grade 5 material, which is also known as 6AL-4V. Due to its excellent strength-to-weight ratio and corrosion resistance, it is the material most often used. The use of heat treatment may also increase the strength of Grade 5 material.
It is widely used in:
Sports equipment
Aerospace
Marine
Automotive
High-performance
