TITANIUM
Titanium is a lightweight and strong metal, known for its excellent corrosion resistance and extremely favorable strength-to-weight ratio. Thanks to these properties, titanium is widely used in industries such as aerospace, medical, and chemical.
Properties of Titanium
Mechanical and Physical Properties
| Property | Typical Value |
| Density | 4.51 g/cm³ |
| Melting Point | 1668 °C |
| Tensile Strength | 434 MPa (pure Ti) |
| Elastic Modulus | 116 GPa |
| Thermal Conductivity | 21.9 W/m·K |
| Elongation | 30% |
Chemical Composition
Commercially pure titanium contains at least 99% titanium, with small amounts of oxygen, nitrogen, carbon, and iron as impurities. Titanium alloys may include elements such as aluminum, vanadium, and molybdenum to further enhance mechanical properties and corrosion resistance.
