This document specifies the requirements for two wrought cobalt 28-chromium 6-molybdenum alloys
used for surgical implants. The properties apply specifically to wrought bar, rod and wire.
NOTE 1 The mechanical properties of a sample obtained from a finished product made of this alloy can differ
from those specified in this document.
NOTE 2 The high carbon content of this alloy produces a structure containing a significant carbide distribution.
This can be adjusted either in the production of the bar or in subsequent thermomechanical processing to
produce the final device. Carbide distribution in the final device is not included as part of this document.
