- Fatigue strength: 400-500 MPa (at 10⁷ cycles)
- Operating temperature range: -40°C to 400°C
- Good impact resistance
- Magnetic properties
The strength-to-weight proportion intensely favors titanium, conveying proportionate or prevalent quality at essentially decreased mass. This characteristic demonstrates basic in aviation screws where weight lessening specifically impacts fuel productivity and payload capacity. Testing information from aviation applications appears titanium latches keep up 95% of their starting quality after 20 a long time of benefit, whereas steel choices ordinarily hold 85-90% quality over comparable periods. If you require high-strength screws for applications including cyclic stacking or extraordinary temperature varieties, titanium countersunk screws and other titanium combination alternatives give predominant long-term reliability.
Cost Considerations and Long-term Value
