Applications of Co-Cr-Mo Alloy
Prosthetic devices and surgical implants as well as high temperature materials.
|
CastCon is a new manufacturing approach capable of
producing parts with a wide variety of sizes, shapes,
materials and structural characteristics. The mechanical
properties of CastCon parts can be as good as those of
wrought materials. Applications of Co-Cr-Mo Alloy Prosthetic devices and surgical implants as well as high temperature materials. |
