1. Density: The density of TC4 titanium alloy is about 4.43 g/cm ³, which is lighter than traditional metals such as steel and copper;

2. Elastic modulus: The elastic modulus of TC4 titanium alloy is about 110 GPa, which is lower than that of steel, but its strength is comparable. This allows it to produce moderate elastic deformation under stress, exhibiting good flexibility and deformation resistance, and can absorb vibrations during cycling, improving riding comfort.

3. Corrosion resistance: Titanium alloy has good corrosion resistance and can maintain stability in humid and corrosive environments.

These characteristics make titanium alloy an ideal material for high-performance bicycle spokes, reducing the weight of the bicycle while ensuring the strength and durability of the spokes.
