Application description of medical titanium alloy strip and foil materials
2025-12-24
Medical titanium alloy strip (usually 0.1-1.0mm thick) and foil (less than 0.1mm thick) are mainly suitable for the manufacturing of minimally invasive interventional instruments, precision implants, and medical consumables in the medical field due to their excellent biocompatibility, resistance to body fluid corrosion, and lightweight, precision cutting, and easy welding characteristics. Their core applications cover cardiovascular, orthopedic, dental, surgical, and medical aesthetics fields. The two materials have their own focuses on their applications due to thickness differences. Specifically, in the field of cardiovascular, medical titanium alloy strip can be used to manufacture support substrates for vascular stents and membrane skeletons for cardiac occluders. High precision structural components are made through precision rolling and laser cutting processes, which have certain strength and flexibility and can adapt to vascular dilation. The requirement for dynamic cardiac activity ensures stability after implantation; Micro bone plates and thin connecting plates for spinal fixation systems can be processed in orthopedics to meet the fixation needs of narrow bone areas and reduce compression on surrounding tissues; In dentistry, it can be used as a base pad for dental implants and a thin bracket for oral restorations. With its lightweight characteristics, it conforms to the anatomical structure of the oral cavity, ensuring the comfort and stability of the restoration effect; In addition, it can also be used as a cutting edge substrate for surgical instruments and as an outer reinforcement band for minimally invasive instruments, enhancing the wear resistance and structural strength of the instruments. In terms of medical titanium alloy foil, due to its extreme thinness and stronger processability, it is mainly used for high-precision implant and consumable manufacturing. In the cardiovascular department, it can be used to make thin leaflets for artificial heart valves and inner foil layers for vascular intervention catheters, which can achieve precise flexible movements and blood compatibility, reducing interference with blood flow; In the field of medical aesthetics, ultra-thin support foils for thread embedding and micro foil scaffolds for local shaping can be used to reduce postoperative foreign body sensation due to their thin, light, and soft characteristics. They also have excellent biocompatibility and fast postoperative recovery; In surgery, it can be used as an ultra-thin patch substrate for visceral repair and a lubricating foil layer for minimally invasive puncture needles, suitable for the needs of fine tissue repair and minimally invasive operations; In addition, it can also be used as electrode foil layer for medical sensors and insulation foil layer for implantable medical devices, balancing biocompatibility and conductivity/insulation performance to ensure precise operation of the devices.
