Alloy dental material Mediloy® M-Co

cobalt-chromiumCoCrfor dental crowns

Product overview
Mediloy® M-Co CAD/CAM milling blanks are Co-Cr alloy blocks manufactured in Germany for dental restorations. Designed for efficient CAD/CAM milling, they are compatible with BEGO partial denture alloys, Wirobond® C+ SLM frameworks and units milled from Mediloy® M-Co (crowns, secondary crowns).

Economic advantages
Excellent milling properties reduce tool wear and lower tool-related costs over time. Compare your previous cost per milled unit (including tool wear) with Mediloy® M-Co to evaluate savings in production.

Your advantages

• Type 4 alloy (ISO 22674)
• Approved for crowns and bridges, metal-ceramics and implant prosthetics
• Biocompatible and corrosion-resistant like all BEGO alloys*
• Special heat treatment provides:
  • reduced tool wear during milling
  • a homogeneous microstructure without cavities or porosities
  • particularly easy machinability
• Reduced hardness of 290 HV10 for easier processing
• Available sizes:
  • without shoulder: 8, 10, 12, 14, 16, 18, 20, 22 and 25 mm
  • with shoulder: 12, 14, 16, 18, 20, 22 and 25 mm
