Titanium (Ti6Al4v)
Ti6Al4V titanium has excellent mechanical properties and corrosion resistance, in addition to having a low specific weight and remarkable biocompatibility qualities.
Ti6Al4V titanium is ideal for many high performance engineering applications, such as the aerospace industry or that of motorsport, and it is perfect for the production of biomedical implants.
It is used both for rapid 3D modelling with metal powder as well as for wire EDM and welding processes.
