ASTM F75 CoCrMo (UNS R30075) is a cobalt-chromium-molybdenum (CoCrMo) alloy widely used in biomedical applications, particularly for orthopedic implants such as hip and knee replacements, as well as dental prosthetics. It belongs to the castable cobalt-based alloy family and is known for its excellent wear resistance, corrosion resistance, and biocompatibility.

Standards & Specifications

  • ASTM F75: Standard for CoCrMo alloy castings.
  • ISO 5832-4: International standard for implantable CoCrMo alloys.
  • UNS R30075: Unified Numbering System designation.

Typical applications of ASTM F75 CoCrMo Alloy:

  • Orthopedic Implants: Hip stems, femoral knees, joint replacements.
  • Dental Implants & Prosthetics: Crowns, bridges, and denture frameworks.
  • Surgical Instruments: Due to corrosion resistance and durability.

Key Characteristics

High corrosion resistance (due to passive Cr oxide layer)
Excellent biocompatibility (ISO 5832-4, ASTM F75 compliant)
Superior wear resistance (low friction in joint replacements)
Good mechanical strength and toughness
Resistant to pitting and crevice corrosion in physiological environments

Manufacturing & Processing

Investment Casting (Lost-Wax Process): Most common method for producing ASTM F75 implants.
Hot Isostatic Pressing (HIP): Used to eliminate porosity and improve mechanical properties.
Heat Treatment: Solution annealing can refine microstructure.
Machining: Difficult due to hardness; often requires grinding or EDM.
