ASTM F562 specifies the requirements for wrought 35cobalt-35nickel-20chromium-10molybdenum alloy (UNS R30035) in bar and wire forms used in the manufacture of surgical implants. This cobalt-based superalloy achieves its exceptional mechanical properties through a combination of work strengthening and aging, delivering ultra-high strength (up to 300 ksi), outstanding corrosion resistance, excellent ductility, and superior fatigue life. It is the material of choice for high-strength implantable devices requiring long-term reliability in physiological environments.
