The baseplate and the bridges are crafted in grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, ensuring the gear train functions smoothly. The alloy is 90% titanium, 6% aluminium and 4% vanadium. This combination enhances the alloy’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automotive industries. The use of micro-blasted grade 5 titanium in combination with a grey electroplasma treatment confers great rigidity on the entire assembly and provides rigorously even surfaces.

The skeletonised baseplate and the bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.
