Medical Titanium Wire
Ultra-Clean Titanium Wire for OEMs
Medical titanium wire refers to titanium and titanium alloy wire that complies with relevant international or national medical device standards and is intended for implantation in the human body or for long-term/short-term contact with human tissue. It is typically produced from commercially pure titanium or medical-grade titanium alloys through vacuum melting, hot working, and precision wire drawing. Medical titanium wire features excellent biocompatibility, corrosion resistance, high strength, low elastic modulus, and good machinability, making it suitable for applications such as orthopedic binding, dental implants, surgical instruments, and cardiovascular interventional devices, ensuring safety and stability in both long-term and short-term human contact.

Application Areas & Case Studies
Medical titanium wire is widely used in orthopedic implant fixation, dental implants, surgical instruments, and cardiovascular interventional devices. Orthopedic and spinal applications require strict control over mechanical property stability, uniform internal structure, and non-destructive testing standards. Dental applications place higher emphasis on precise small-diameter dimensions, surface quality, and machining consistency. Surgical instruments prioritize corrosion resistance and machining stability for repeated sterilization. Cardiovascular-related applications demand high material cleanliness and precise dimensional control.
We have long supplied medical titanium wire to domestic medical device manufacturers as well as customers in Europe and North America, covering applications such as orthopedic fixation, dental implants, and surgical instruments, with stable and continuous supply across multiple grades and specifications. Leveraging a comprehensive quality control system, we provide customized solutions including non-standard diameters (incremental 0.1 mm or 0.5 mm), fixed-length or short-length deliveries, various surface conditions, and special mechanical property requirements.
