The density of Titanium (Ti) is approximately:
4.51 g/cm³ (or 4510 kg/m³)
Key Notes:
This value applies to commercially pure titanium (e.g., Grade 2).
Titanium alloys may have slightly different densities depending on alloying elements.
Titanium is much less dense than steel (~7.85 g/cm³) but denser than aluminum (~2.70 g/cm³).
Its high strength-to-weight ratio makes it ideal for aerospace, medical implants, and high-performance engineering applications.
Comparison of densities between Titanium and other common metals, along with typical applications:
| Metal | Density (g/cm³) | Relative Density | Typical Applications |
|---|---|---|---|
| Titanium (Ti) | 4.51 | Medium | Aerospace, medical implants, marine, high-end sports equipment |
| Aluminum (Al) | 2.70 | Low | Aircraft, packaging, automotive, construction |
| Steel | 7.85 | High | Construction, tools, machinery, pipelines |
| Copper (Cu) | 8.96 | High | Electrical wiring, plumbing, electronics |
| Nickel (Ni) | 8.90 | High | Alloys, batteries, plating |
| Magnesium (Mg) | 1.74 | Very Low | Lightweight parts in aerospace and electronics |
| Zinc (Zn) | 7.14 | High | Galvanization, die casting |
| Lead (Pb) | 11.34 | Very High | Radiation shielding, batteries, weights |
| Tungsten (W) | 19.25 | Extremely High | High-temperature tools, aerospace, ballast |
Why Titanium Stands Out:
Lightweight but strong: Almost as strong as steel but 45% lighter.
Excellent corrosion resistance, especially in seawater and bodily fluids.
Biocompatible, making it perfect for surgical implants.
Used in jet engines, airframes, prosthetics, and luxury watches.
