Cobalt Chrome is a fine powder mixture superalloy characterized by having excellent mechanical properties (strength, hardness, etc.), corrosion resistance, and temperature resistance. Such alloys are commonly used in biomedical applications such as dental and medical implants and also for high-temperature engineering applications such as aero engines.
- Part-building applications, such as functional metal prototypes, small series products, individualized products, or spare parts
- High-temperature and high-stress aerospace components
- Surgical devices
- Medical implants
