Material with spring characteristic

Material with spring characteristic

Material with spring characteristic

(OP)
We are looking for a convenient material having spring characteristic also having good corrosion and fatigue resistance. This is a part of a knee joint which is used by people  having artificial limbs. The frequesncy of the load on the part is 1/3 Hz as it indicates that the dynamic force effect with respect to the time during the gait of a human. If you can send me your e-mail, I can also send you the figure of the application and the a part.
 
Also I would like to know whether the geometry of the material is also important on the spring action. Any help would be appreciated.

RE: Material with spring characteristic

You will be extremely limited on the materials that can be used in an artificial joint.  Titanium alloys and low-Ni stainless steels are most frequently for implants.  Co-Cr alloys are also used, but I am not familiar with them being used in spring applications.  Regarding geometry, this will have a HUGE effect on the spring characteristics, so please post additional details-- shape, thickness, etc.
