CarTech BioDur CCM Plus alloy is a non-magnetic, cobalt-chromium-molybdenum alloy exhibiting high strength, corrosion resistance, and wear resistance.

This alloy is a high carbon version of CarTech BioDur CCM alloy and meets the requirements of ASTM F1537, ASTM F799, ISO 5832-12 and ISO 5832-4.

CarTech BioDur CCM Plus alloy is a wrought powder metallurgy product 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 steel-making practices to produce finished products.

CarTech BioDur CCM Plus alloy possesses the following product attributes:

* homogeneous chemistry and microstructure;

* small, uniformly distributed carbides, typically less than 10 microns in length as measured on longitudinal sections;

* fine austenitic grain size, typically ASTM E112 grain size number 12 and finer for hot rolled material and 10-11 and finer for material annealed at 2050/2100°F (1121/1149°C) for 1 hour and water quenched;

* improved forgeability over CarTech BioDur CCM alloy;

* meets ASTM F799 requirements without requiring thermomechanical processing;

* retains a high strength level after high temperature annealing;

* improved machinability over CarTech BioDur CCM alloy.

Because CarTech BioDur CCM Plus alloy does not require thermomechanical processing in order to meet ASTM F799 mechanical property requirements, normally supplies the finished product in the hot worked condition.

Applications:
CarTech BioDur CCM Plus alloy should be considered as a candidate for use in the orthopedic industry for joint replacement and fracture fixation devices such as total hip, knee, and shoulder replacements, especially when wear or fatigue properties are of major importance or where intricate high strength forgings are required.

CarTech BioDur CCM Plus alloy should be considered for use in producing large forgings where it is difficult to attain ASTM F799 properties throughout the forging's cross section due to a lack of sufficient thermomechanical processing. Applications have included hip and knee forgings and machined modular femoral heads for metal-metal and metal-HDPE wear couples.
