Cobalt-chrome-molybdenum CCM ASTM F1537 Alloy 1

Technical Data Sheet

This alloy of Cobalt-Chromium-Molybdenum for implants is the MicroMelt® Biodur® Carpenter CCM® alloy (Cobalt CCM ASTM F1537). It meets the strictest requirements regarding biocompatibility and corrosion resistance. It is produced by powder metallurgy resulting in an exceptionally fine microstructure. But is also tough, ductile, hard, as well as fatigue and wear resistant. Its high cobalt content may impair its machinability and its cold deformability is difficult. It is non-magnetic.

Cobalt CCM ASTM F1537 is especially applicable for medical implants (endoprothesis and osteosynthesis) wherever high mechanical stress is expected. It is also widely used in the watch making industry as well as other industries where hardness, toughness, ductility and corrosion resistance are required.
