The Charm of Titanium Alloy to Other Metals
| Property | Titanium alloy (Ti-6Al-4V) | Aluminum alloy (6061) | Stainless steel (316L) | Brass (C36000) |
| Density (g/cm ³) | 4.43 | 2.70 | 8.00 | 8.50 |
| Tensile strength (MPa) | 951-1186 | 276 | 515 | 310 |
| Strength to weight ratio | Highest(215 MPa·cm³/g) | Medium (102 MPa · cm ³/g) | Low (64 MPa · cm ³/g) | Minimum (39 MPa · cm ³/g) |
| Corrosion resistance | Extremely strong | Medium (requiring anodizing) | Strong (resistant to general corrosion) | Weak (easily oxidized) |
| Maximum temperature resistance (° C) | 400-500 | 150-200 | 800 | 200 |
| Thermal conductivity (W/m · K) | 6.7 | 167 | 16.2 | 120 |
| Biocompatibility | Excellent (Medical Implant) | NO | Moderate (for some medical purposes) | NO |
| Processing difficulty | Extremely high (easy to stick to knives, heat accumulation) | Low (easy to cut) | Medium (requires specialized tools) | Low (high machinability) |
Detailed description of the advantages
2. Corrosion resistance in extreme environments
Titanium alloy has almost no corrosion in seawater and chloride ion environments (such as the service life of ship propeller shafts can reach more than 20 years), while 316L stainless steel may still experience pitting corrosion in long-term seawater immersion. In the medical industry, titanium implants have no risk of ion precipitation in the human body, while stainless steel requires surface passivation treatment.
4. Biocompatibility and non-magnetic properties
Titanium alloy is the only metal that can be implanted into the human body for a long time (such as bone screws and dental implants), and is non-magnetic, suitable for internal parts of MRI equipment. In contrast, stainless steel may interfere with magnetic fields and pose a risk of nickel allergy.
Comparison of Typical Application Scenarios
| Industry | Typical Applications of Titanium Alloy | Limitations of alternative materials |
| EADS | Engine blades, fuselage structural components | Insufficient strength of aluminum alloy and excessive weight of steel |
| Medical treatment | Artificial joint and skull fixation system | Poor biocompatibility of stainless steel |
| Ship | Shell and valve of deep-sea detector | Insufficient corrosion resistance of brass |
| Automative | Racing linkage, suspension spring | Insufficient high-temperature performance of aluminum alloy |
