Cobalt, nickel-based alloys are commonly used in the dental industry to make dental restorations.
Cobalt, nickel-based alloys are commonly used in the dental industry to make dental restorations. Because of their good mechanical properties and biology compatibility, they have become the best economic substitutes for gold and silver based alloys ( precious metals ).
Currently, we offer StelliteC5 cobalt-based and StelliteN9 nickel-based alloys for porcelain-fused-to-metal alloys and StelliteC3 cobalt-based alloys for bracket alloys. For the health of users, our dental alloys do not contain beryllium, cadmium and other elements. In order to adapt to the development of technology, we also provide customers with alloy powder products suitable for 3D printing process.
In order to produce dental alloys with high standards and meeting customer requirements, Kennametal Stellite has obtained ISO 13485 medical system and CE certification, and completed FDA registration in the United States;
