ThermoFit® is the original ZEISS carbon fiber technology. Exclusively developed for metrology. It's the best combination of very high stiffness, light weight and thermal stability.
Extensions made of aluminum are characterized by high stiffness and light weight. In regard of thermal stability, aluminium is not the best choice.
Titanium is the cost-efficient alternative. Its characteristics therefore are behind carbon fiber and aluminum.
