Moreover, Co round bars have strong resistance to traction and excellent workability, which are smooth, also compact surface. Regarding to Co properties its reduce the oxide formation, with a low specific weigth and excellent mechanical properties. All in all, the bars have good biocompability and suitable mechanical and physical properties for Dental Industry
