CoCrMo Dental disc

Product Description

Cobalt Based Dental Alloy CoCrMo investment casting disc diameter 98mm


Cobalt-chrome or cobalt-chromium (CoCr) is a metal alloy of cobalt and chromium. Cobalt-chrome has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants.


CoCrMo milling disc with excellent properties for the manufacture of crowns, bridges, frameworks, telescopes, bars, attachments, implant supported superstructures and abutments. MoguCera C Disc is based on a non-precious ceramic alloy already used in the conventional casting technology. Free of nickel, beryllium, lead und cadmium. Type 4 pursuant to DIN EN ISO 22674 with a very wide range of indications.


Composition: Co60-65%,Cr25-30%,Mo5-7%

Co-Cr alloys show high resistance to corrosion due to the spontaneous formation of a protective passive film composed of mostly Cr2O3, and minor amounts of cobalt and other metal oxides on the surface. As its wide application in biomedical industry indicates, Co-Cr alloys are well known for their biocompatibility. Biocompatibility also depends on the film and how this oxidized surface interacts with physiological environment.Good mechanical properties that are similar to stainless steel are a result of a multiphase structure and precipitation of carbides, which increase the hardness of Co-Cr alloys tremendously. The hardness of Co-Cr alloys varies ranging 550-800 MPa, and tensile strength varies ranging 145-270 MPa. Moreover, tensile and fatigue strength increases radically as they are heat-treated. However, Co-Cr alloys tend to have low ductility, which can cause component fracture. This is a concern as the alloys are commonly used in hip replacements. In order to overcome the low ductility, nickel, carbon, and/or nitrogen are added. These elements stabilize the γ phase, which has better mechanical properties compared to other phases of Co-Cr alloys.
