Medical Titanium Wire

Medical titanium wire is a pure titanium/low-alloy titanium wire product specially developed for the medical field, with excellent biocompatibility and precise size control as its core advantages. It fully complies with international standards such as ASTM F67 (pure titanium medical standard) and ISO 5832-1, and is widely used in orthopedic implants, minimally invasive cardiovascular surgery, dental instruments, and other scenarios worldwide. As a key material that comes into direct contact with human tissue or body fluids, its performance needs to meet the triple requirements of "non allergenic+corrosion-resistant+easy to form", and it is the core basic material for high-end medical device manufacturing.

The size parameters of medical titanium wire are deeply adapted to the needs of medical scenarios, with a conventional diameter range covering 0.01mm-3.0mm. It can be customized with 0.008mm ultra-fine specifications (for cardiac stent guide wires) and 5.0mm thick specifications (for orthopedic fixation needles); The diameter tolerance is strictly controlled within ± 0.001mm (ultra-fine specification) to ± 0.01mm (medium coarse specification) to ensure the operational accuracy of minimally invasive surgical instruments; The surface treatment focuses on "low stimulation" and provides two solutions: mirror polishing (Ra ≤ 0.2 μ m, reducing tissue friction damage) and acid pickling passivation (removing oxide layer, avoiding impurity dissolution), both of which have passed biocompatibility testing (cytotoxicity, sensitization testing).

Medical titanium wire is mainly made of pure titanium and low-alloy titanium grades, suitable for different medical purposes. GR1 pure titanium wire has a titanium purity of ≥ 99.5%, extremely low impurity content (iron ≤ 0.25%, oxygen ≤ 0.18%), optimal biocompatibility, strong resistance to body fluid corrosion, and is suitable for long-term implantation scenarios (such as orthopedic sutures and cochlear implant fixation wires); GR2 pure titanium wire has slightly higher strength than GR1 (tensile strength 345-450MPa), is easy to process and shape, and is more suitable for reusable surgical instruments (such as laparoscopic forceps wire); GR9 (Ti-3Al-2.5V) low-alloy titanium wire balances strength and flexibility, and can be bent into complex shapes, making it suitable for instruments that require frequent deformation such as cardiovascular guide wires and dental orthodontic wires.

The core advantages of medical titanium wire focus on pain points in medical scenarios, and its biocompatibility can achieve "long-term coexistence with human tissues", without sensitization or toxicity, avoiding tissue irritation caused by metal ion dissolution; It can form a stable oxide film in the environment of body fluids (pH=7.2-7.4), and can be implanted for a long time without corrosion or degradation, with a service life of more than 10 years; Mechanical properties are suitable for medical needs, with an elongation rate of ≥ 18% (pure titanium grade), which can achieve ultra-fine drawing and complex winding forming, meeting the strength requirements of orthopedic fixation and adapting to the flexible operation of minimally invasive surgical instruments.

In terms of quality and service assurance, each batch of medical titanium wires has undergone laser diameter measurement, tensile testing, electrochemical corrosion testing, and biocompatibility testing, and can provide complete COA (analysis report) and DMF filing materials; Support small batch customization (minimum order quantity 0.1kg) and fixed length cutting (accuracy ± 0.5mm) to meet the needs of instrument research and mass production; Cooperate with international medical logistics to provide temperature controlled transportation (to avoid material oxidation) and customs special supervision clearance services, ensuring fast and compliant delivery of products. If further docking is required, we can provide compatibility testing reports or device adaptation plans for medical titanium wires and human tissues to assist customers in promoting product certification.
