APPLICATION
- Avoid wall thicknesses of less than 0.35 mm
- Design the connectors as strong as possible (height: at least 3.5 mm, width: at least 2.5 mm)
- Please use suitable milling tools and cutting data according to the manufacturer's instructions for the dental milling machines. CORiTEC CoCr M6 disc can be machined with common CoCr strategies.
- For veneering use commercially available dental ceramics for cobalt based metal alloys with a suitable coefficient of linear thermal expansion.
- CORiTEC CoCr M6 is solderable and weldable.
- Safety note: Metal dusts are harmful to health. Use a dust extractor. Consider allergic hypersensitivities to contents of the alloy. In case of suspected incompatibility with individual elements of this alloy it should not be used.
