CarTech Micro-Melt BioDur CCM alloy is a non-magnetic, cobalt-chromium-molybdenum wrought alloy exhibiting high strength, corrosion resistance, and wear resistance. This alloy is a powder metallurgy version of CarTech BioDur CCM alloy (ASTM F 1537 Alloy 1), which is a high nitrogen, low carbon wrought version of ASTM F 75 cast alloy.

CarTech Micro-Melt BioDur Carpenter CCM alloy is produced by vacuum induction melting (VIM) followed by gas atomization and hot isostatic pressing to produce 100% dense billets. These billets are then processed by conventional steelmaking practices to produce millform products such as billet, bar and wire that are subsequently processed into finished articles. Hot isostatically pressed (HIP'd) near net shapes and loose powder are also available for processing into finished articles.

CarTech Micro-Melt BioDur CCM alloy possesses the following product attributes:

• homogeneous chemistry and microstructure;

• small, uniformly distributed carbides, typically less than 5 microns in length as measured on longitudinal sections;

• higher yield strength and ultimate tensile strength than cast-wrought BioDur Carpenter CCM alloy in the warm-worked or annealed conditions;

• higher hardness than cast-wrought BioDur Carpenter CCM alloy in the warm -worked or annealed conditions

• finer grain size than cast-wrought BioDur Carpenter CCM alloy in the warm- worked or annealed conditions;

• higher rotating beam fatigue strength than cast-wrought BioDur Carpenter CCM alloy in the warm-worked condition.

Carpenter generally supplies CarTech Micro-Melt BioDur CCM alloy in the warm-worked condition since this condition provides the highest mechanical properties, highest hardness, finest grain size, and highest fatigue strength.

Applications:
CarTech Micro-Melt BioDur CCM alloy has been used in the orthopedic implant industry for joint replacement and fracture fixation devices such as total hip, knee, and shoulder replacements. This alloy is particularly suited for small diameter bar and wire applications, where high strength or high fatigue resistance is required.
