Titanium Biocompatibility
Titanium is one of the most biocompatible metals known to science. The human body does not mount an immune response against titanium, and bone tissue grows directly onto titanium surfaces through a process called osseointegration. This biological integration makes titanium the material of choice for permanent implants that must remain in the body for the patient's lifetime. Ti-6Al-4V ELI (Grade 23, Extra Low Interstitials) is the standard alloy for load-bearing implants, with tighter controls on oxygen and iron content that enhance fracture toughness and fatigue resistance in the biological environment.
Implant Components We Produce
CastAlloy manufactures titanium medical components including hip replacement femoral stems and acetabular cups, knee replacement tibial baseplates and femoral components, spinal fusion cages, pedicle screws, and rods, dental implant bodies and abutments, trauma fixation plates, screws, and intramedullary nails, and custom patient-specific implants. Manufacturing methods include investment casting for complex near-net geometries (hip stems, knee components) and precision CNC machining from bar stock for cylindrical components (dental implants, pedicle screws).
Medical Quality Systems
Medical implant manufacturing requires quality systems that ensure patient safety and regulatory compliance. CastAlloy's quality system supports full material traceability per ASTM F136 (Ti-6Al-4V ELI), biocompatibility documentation, surface finish verification critical for osseointegration, and complete device history record (DHR) documentation compatible with FDA 21 CFR Part 820 and ISO 13485 requirements.
