Characteristics of Titanium
Highest Specific Strength Among Structural Metals
Titanium is a remarkable metal known for being lightweight, strong, and highly resistant to rusting—even under seawater.
Its density is about half that of iron, yet its strength is comparable to steel.
Titanium also offers excellent corrosion resistance, demonstrating complete resistance to seawater. It is non-toxic and safe for use in the human body.
Titanium is not significantly affected by welding, machining, heat treatment, or aging over time. It is also easy to recycle, making it an environmentally friendly metal.
This section offers a detailed look at the characteristics of titanium.
Lightweight, Strong, Rust-Resistant
| Property | Description | Typical Applications |
|---|---|---|
| Excellent corrosion resistance | Completely resistant to seawater | Heat exchangers, building materials |
| Lightweight | Approximately 60% lighter than stainless steel | Aircraft engines |
| High strength | Tensile strength of 275–735 MPa for commercially pure titanium, 620–1,800 MPa for titanium alloys | |
| High elasticity | Elastic modulus is about 50% that of stainless steel | Golf club heads, springs |
| Excellent low-temperature toughness | Commercially pure titanium and titanium alloys are both ductile at extremely low temperatures | Liquid oxygen tanks |
Safety
