| Density | Approximately 4.51 g/cm³ | Commercially pure titanium and titanium alloys | About 40% lighter than steel, helping reduce component weight while maintaining high structural performance. |
| Tensile Strength | 240–345 MPa for commercially pure grades Up to approximately 900–1,100 MPa for Grade 5 alloy | Commercially pure titanium; Ti-6Al-4V | Supports load-bearing parts, especially when strength-to-weight ratio is a primary design requirement. |
| Yield Strength | 170–275 MPa for commercially pure grades Approximately 830–950 MPa for Grade 5 alloy | Typical annealed material conditions | Indicates the stress level at which permanent deformation begins; actual values depend on grade, heat treatment, and product form. |
| Elastic Modulus | Approximately 105–120 GPa | Most titanium grades at room temperature | Lower than steel, allowing useful flexibility but requiring careful consideration of part stiffness and deflection. |
| Specific Strength | High strength-to-weight ratio | Particularly notable for Ti-6Al-4V and other alpha-beta alloys | Enables lightweight designs for aerospace, medical, chemical-processing, and high-performance industrial components. |
| Melting Range | Approximately 1,660–1,670°C for commercially pure titanium Approximately 1,600–1,660°C for common alloys | Grade and alloy dependent | Provides excellent high-temperature capability, although allowable service temperature also depends on environment and exposure time. |
| Thermal Conductivity | Approximately 6–22 W/m·K | Lower than aluminum and most steels; varies by grade | Low thermal conductivity can increase heat concentration during machining and requires appropriate cutting parameters and cooling practices. |
| Coefficient of Thermal Expansion | Approximately 8.5–9.5 × 10−6/K | Typical room-temperature range | Lower thermal expansion helps dimensional stability across temperature changes compared with many aluminum alloys. |
| Corrosion Resistance | Excellent in seawater, chlorides, and many oxidizing environments | Protective, self-healing titanium oxide film | Reduces the need for protective coatings and supports long service life in marine, chemical, and medical applications. |
| Biocompatibility | Generally high for suitable implant-grade titanium | Commercially pure titanium and Ti-6Al-4V ELI, when processed to applicable standards | Makes titanium suitable for many orthopedic, dental, and surgical components; final suitability depends on standards, surface condition, and application. |
| Magnetic Behavior | Essentially non-ferromagnetic | Commercially pure titanium and common titanium alloys | Useful for applications requiring low magnetic interference, subject to the complete assembly and surrounding materials. |
| Fatigue Performance | Strong fatigue capability when properly designed and finished | Influenced by alloy, surface finish, stress concentration, and environment | Supports cyclic-load applications, but machining marks, sharp transitions, and surface defects should be controlled. |
| Machinability | More difficult than aluminum and mild steel | All titanium grades; Grade 5 requires particular process control | Low thermal conductivity and chemical reactivity can cause heat buildup, tool wear, and work hardening; rigid setups and suitable tooling are important. |
| Recyclability | Recyclable through controlled scrap collection and remelting | Commercially pure titanium and titanium alloys | Separating alloys and avoiding contamination improves recovery quality and supports more sustainable manufacturing programs. |
