Medical Titanium Bar
ASTM-Certified Titanium Bars for Implants
Medical titanium bars refer to titanium and titanium alloy bar products that comply with relevant international or national medical device standards and are intended for implantation in the human body or for long-term or short-term contact with human tissue. They are typically manufactured from commercially pure titanium or medical-grade titanium alloys through vacuum melting, hot working, and precision forming processes. Medical titanium bars offer excellent biocompatibility, outstanding corrosion resistance, high strength, low elastic modulus, and good machinability, enabling safe and stable long-term use in orthopedic, dental, and various surgical implant and medical device applications.
As a professional manufacturer of medical titanium bars, we provide a stable supply of multiple medical grades, with standard diameters ranging from small-size precision bars to large-diameter forged bars. We support customized services such as fixed-length cutting, ultrasonic testing, and surface condition control, and are equipped with a complete inspection system covering chemical composition analysis, mechanical property testing, ultrasonic inspection, metallographic examination, and dimensional accuracy control, ensuring high consistency and full traceability for every batch supplied for medical applications.

Application Areas & Case Studies
Medical titanium bars are widely used in orthopedic implants, dental implants, surgical instruments, and cardiovascular interventional devices. Orthopedic and spinal implants place strict requirements on the stability of mechanical properties, internal structural uniformity, and non-destructive testing standards. Dental implants focus more on small-diameter dimensional accuracy, surface quality, and machining consistency. Surgical instruments emphasize corrosion resistance and machining stability to withstand repeated sterilization, while cardiovascular-related applications demand higher levels of material cleanliness and precise dimensional control.
We have long supplied medical titanium bars to domestic medical device manufacturers as well as medical customers in Europe and North America, covering applications such as orthopedic implants, dental implants, and surgical instruments, with stable and continuous supply across multiple grades and specifications. Supported by a comprehensive quality control system, we offer customized solutions including non-standard diameters (in 0.5 mm increments), fixed-length or short-length delivery, various surface conditions, and special performance requirements. This enables us to balance consistent quality with flexible lead times, meeting the medical industry’s high standards for safety and reliability.
