Grade 5 titanium is a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% titanium, 6% aluminum and 4% vanadium.
This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automobile industries.
The baseplate and bridges have been subjected to intensive and complete validation tests to optimise their resistance capacities.
