Material Characteristics
Biocompatibility: Excellent integration with human bone and tissue without rejection
Superior Corrosion Resistance: Withstands physiological saline, blood, and body fluids for long-term implantation
High Strength-to-Weight Ratio: 40% lighter than steel while maintaining strength
Non-Toxic and Non-Magnetic: Safe for MRI and other sensitive medical equipment
Manufacturing Process
Melting: Electron Beam Melting (EBM) or Vacuum Arc Remelting (VAR) for high purity
Forging: Hot forging to enhance density and eliminate internal defects
Rolling/Drawing: Precision forming to required dimensions
Annealing: Stress relief and toughness improvement
Surface Treatment: Pickling or polishing for clean, smooth surfaces
Machining Characteristics
- Suitable for precision cold working (turning, drilling, milling)
- Excellent weldability with inert gas protection, producing strong welds
Testing Requirements
- Chemical analysis using spectrometry or ICP-MS
- Mechanical testing (tensile, compression, hardness) per medical standards
- Non-destructive testing (ultrasonic, X-ray) for internal integrity
- Surface inspection for defects and contamination
- Biocompatibility testing (cytotoxicity, hemocompatibility)
Applications
Orthopedic implants: Intramedullary nails, bone plates, hip and knee replacements
Dental implants: Root implants for permanent gingival integration
Surgical instruments: Corrosion-resistant forceps, bone saws, suturing devices
Spinal implants: Disc prostheses and screw fixation systems
Cardiovascular devices: Heart valves, pacemaker housings
