GR2 Titanium Screws Application
GR2 titanium (commercially pure titanium) is widely used in high-performance racing models (RC cars, drones, miniature race vehicles) due to its lightweight, corrosion resistance, and durability. Below are its key advantages and applications:
1. Why Use GR2 Titanium Screws in Racing Models?
(1) Extreme Lightweight
- Density: 4.5 g/cm³ (vs. steel’s 7.8 g/cm³) → Reduces unsprung weight, improving acceleration & handling.
- Example: Replacing steel screws in an RC car can save 5-10g per wheel, enhancing cornering speed.
(2) Corrosion Resistance
- No rust or oxidation even in wet/muddy conditions (unlike steel).
- Perfect for: Off-road RC racing, drone components exposed to moisture.
(3) Good Strength for Small Fasteners
- Tensile Strength: ~345 MPa (weaker than GR5 but sufficient for small screws in low-stress areas).
- Best for: Non-load-bearing parts (body panels, trim, electronics mounts).
(4) Non-Magnetic & Non-Sparking
- Safe for electronic components (no interference with sensors/motors).
- Useful in hydrogen-powered or explosive environments (e.g., fuel system screws).
2. Common Uses in Racing Models
| Application | Benefit of GR2 Titanium |
|---|---|
| RC Car Chassis Screws | Lighter than steel, reduces overall weight for better lap times. |
| Drone Frame Fasteners | Corrosion-resistant in humid/rainy conditions. |
| Miniature Motor Mounts | Non-conductive, prevents electrical shorts. |
| Aero Component Attachments | High fatigue resistance for vibration-heavy areas. |
3. Comparison: GR2 vs. GR5 Titanium in Racing Models
| GR2 Titanium (Pure Ti) | GR5 Titanium (Ti-6Al-4V) |
|---|---|
| Lower strength (345 MPa) but lighter | Higher strength (900+ MPa) but heavier |
| Cheaper, good for non-critical parts | Used in high-stress areas (suspension, drivetrain) |
| Easier to machine & thread | Requires anti-galling treatments |
Best Choice for Small Screws: GR2 (cost-effective & sufficiently strong for most racing model needs).
4. Limitations of GR2 Titanium Screws
- Not for high-load applications (e.g., drivetrain, suspension arms – use GR5 instead).
- Softer than steel – Can strip if over-tightened (use a torque wrench).
5. Where to Use GR2 Titanium Screws?
✅ RC Cars (body panels, servo mounts)
✅ Drones & UAVs (frame assembly, camera mounts)
✅ Miniature Racing Boats (saltwater-resistant hardware)
✅ High-Speed Model Aircraft (weight-sensitive fasteners)
