application areas
- Implants
- In orthopedic surgery , it is used for artificial joints and other implants.
- dentures
- For the production of model cast prostheses , because it causes practically no allergic reactions , is corrosion-resistant and light. (See chrome-cobalt-molybdenum alloy )
- Gas turbines
- With the type designation Haynes Alloy 21 , Vitallium is used for the construction of gas turbine blades that are subject to high thermal and mechanical loads.
- Chemical container
- Vitallium containers are used for the storage of aggressive chemicals , as the containers are not attacked at all or only minimally due to the resilience of the alloy.
