The alloy composition used in orthopedic implants is described in industry standard ASTM-F75: mainly cobalt, with 27 to 30% chromium, 5 to 7% molybdenum, and upper limits on other important elements such as less than 1% each of manganese and silicon, less than 0.75% iron, less than 0.5% nickel, and very small amounts of carbon, nitrogen ...
Alacrite (also known as Alloy L-605, Cobalt L-605, Haynes 25, and occasionally F90 [1] [2] [3]) is a family of cobalt-based alloys. The alloy exhibits useful mechanical properties and is oxidation- and sulfidation -resistant.
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
The company's alloys are primarily marketed under the Hastelloy and the Haynes brands. They are based on nickel, but also include cobalt, chromium, molybdenum, tungsten, iron, silicon, manganese, carbon, aluminum, and/or titanium. [2]
ISO 5832-6:1997 Part 6: Wrought cobalt-nickel-chromium-molybdenum alloy; ISO 5832-7:2016 Part 7: Forgeable and cold-formed cobalt-chromium-nickel-molybdenum-iron alloy; ISO 5832-8:1997 Part 8: Wrought cobalt-nickel-chromium-molybdenum- tungsten-iron alloy; ISO 5832-9:2007 Part 9: Wrought high nitrogen stainless steel; ISO 5832-11:2014 Part 11 ...
Alloys with chromium and tungsten carbides are very hard and wear-resistant. [139] Special cobalt-chromium-molybdenum alloys like Vitallium are used for prosthetic parts (hip and knee replacements). [140] Cobalt alloys are also used for dental prosthetics as a useful substitute for nickel, which may be allergenic. [141]
Inconel 690: Low cobalt content for nuclear applications, and low resistivity [71] Inconel 706; Inconel 713C: Precipitation hardenable nickel-chromium base cast alloy [2] Inconel 718: Gamma double prime strengthened with good weldability [72] Inconel 738; Inconel X-750: Commonly used for gas turbine components, including blades, seals and rotors.
