CORiTEC CoCr M6 disc

Brilliant Properties.

  • Type 4 Alloy (EN ISO 22674)
  • Excellent machinability
  • CTLE (α) 25-500 °C: 14,2 10-6*K-1

Suitable for veneering with all conventional metal-ceramics.


CORiTEC CoCr M6 is suitable for (e.g.):

  • thin veneered crowns

  • wide span bridges or bridges with small cross sections

  • partial & full arch dentures

  • clasps, bars, attatchments

  • implant retained superstructures


CORiTEC CoCr M6 disc is a NPM-disc based on Cobalt free from Nickel, Cadmium, Beryllium and Lead. Restorations can be veneered wit all common metal-ceramics with a suitable coefficient of linear thermal expansion (CLTE).

  • 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.
