1) Remark: Wrought cobalt-nickel-chromium-molybdenum alloy for use in the manufacture of forged surgical implants such as prostheses (endoprostheses for hip, knee and elbow) and screws. The material has very good corrosion resistance and shows good ductility and toughness. It is not suitable as an articulation partner against UHMWPE (source: Zimmer Germany GmbH, Freiburg). Typical application: - anchorage components of cemented prostheses
