CTIA GROUP’s tungsten wire tendon ropes are manufactured using high-purity tungsten wire as the primary raw material. They are created through the precision braiding of ultra-fine monofilaments into multi-strand, multi-layer structures. These ropes inherit the excellent physical properties of tungsten while achieving a balance of high strength, flexibility, and stability through structural optimization, making them suitable for high-precision transmission applications such as embodied AI robots.
1. High Density and High Melting Point
With a density approaching 19.25 g/cm3 and a melting point exceeding 3410°C, these ropes maintain structural stability in high-temperature environments without softening or melting. This characteristic provides outstanding heat resistance, making them ideal for medical sterilization, industrial high-temperature operations, and extreme environment applications.
2. High Strength and High Rigidity
The tensile strength of individual filaments can reach 5200–6500 MPa or higher, while the breaking force of the finished rope ranges from hundreds to thousands of Newtons, depending on specifications. Tungsten’s elastic modulus is approximately 411 GPa—significantly higher than that of ordinary steel—ensuring minimal deformation and high rigidity under load, which allows for the effective transmission of force and motion.
3. Low Creep and High Dimensional Stability
Through precision pre-stretching and heat treatment, the ropes exhibit extremely low residual elongation and a creep rate approaching zero under long-term cyclic loading. This ensures the dimensional stability and lasting precision of the transmission system, minimizing performance degradation caused by material elongation.
4. Excellent Fatigue and Bending Resistance
Under conditions such as a tight bending radius (e.g., R=2 mm), the ropes achieve a cyclic lifespan exceeding 2 million cycles while maintaining high strength retention. The multi-strand braided structure ensures uniform stress distribution, enhancing overall fatigue and bending resistance while reducing the risk of wire breakage.
5. Other Physical Properties
Tungsten wire tendon ropes also possess good thermal and electrical conductivity, as well as corrosion and radiation resistance; optimized surface treatments further enhance their wear resistance. The diameter can be customized according to application requirements through CTIA GROUP, balancing compactness with mechanical reliability.
