Arcam ASTM F75 CoCr .

Arcam ASTM F75 CoCr General characteristics Arcam ASTM F75 CoCr is a non-magnetic Cobalt Chrome alloy exhibiting high temperature capability, strength, corrosion resistance, wear resistance as well as excellent biocompatibility. CoCr alloys are widely used within the orthopedics, aerospace, power generation and the dental fields. Within orthopedics, CoCr alloys are typically used where high stiffness or a highly polished and extremely wear-resistant material is required for articulating surfaces. CoCr alloys are commonly used for applications such as knee implants, metal-on-metal hip joints...

Powder characteristics The Arcam ASTM F75 CoCr alloy powder for EBM is a spherical powder with low internal porosity and few satellites produced by gas atomization. The chemical composition complies with the ASTM F75 standard specification. The particle size distribution is 45-100 microns which ensures safe handling of the powder. Material properties CoCr built with the Arcam EBM technology fulfills the ASTM F75 standard with regards to both chemical composition as well as mechanical properties. The material demonstrates excellent strength and ductility. Chemical Composition of Arcam ASTM...

Post Processing Following support structure and powder removal, it is recommended that the parts undergo hot isostatic pressing (HIP) with the following parameters: — 1200 °C — 1000 bar argon — 240 minutes — Free cooling rate Machining Parts produced using the Arcam EBM process demonstrate excellent machineability using any conventional machining process. Horizontal cross section at 50x and 500x magnification The EBM built material allow polishing to mirror-like finish for use as articulating surfaces in knee implants or other applications requiring superior surface finish.
