Medical Grade Ti-6Al-4V ELI Titanium Welding Wire For Implants

Titanium alloys are used in the construction of implants and medical devices for the orthopaedic, spinal, dental, cardiovascular and implantable fields because of their outstanding biocompatibility, corrosion resistance, strength to weight ratio and formability. Ti-6Al-4V ELI (Grade 23) is among the common grades of medical titanium alloys with higher toughness and less oxygen content. It conforms to the ASTM F136 (Medical Titanium Alloy) standard and developed specifically for use in instrument parts that demand a high level of dependability or in long-term implantations.

Medical titanium welding wire are applied in:

Orthopaedic implant welding and fixing (Bone plate,bone nail,spinal stent)

Welding of medical device structural components (surgical instruments, catheter stents, connectors)

Laser/arc welding materials for implantable devices

Welding of medical titanium mesh and titanium wire mesh structures

Medical titanium welding wire must meet strict chemical composition and mechanical performance requirements, and avoid exceeding the standards of oxygen, nitrogen, hydrogen and other elements during the production process. We ensure that each batch of welding wire meets ASTM F136/ASTM B863 standards through vacuum melting, strict composition control, precision drawing and annealing processes, and provide complete quality certificates and traceable material proofs. For medical device customers, we can also provide material biocompatibility reports, third-party testing, and process parameter recommendations according to customer requirements.

Advantages of medical titanium materials are mainly based on their biocompatibility and corrosion resistance. Titanium can establish a stable oxide film in the human body, which can effectively retard the release of metal ions, and the film can also reduce tissue irritation and rejection. Titanium is lighter and more corrosion resistant than stainless steel or cobalt chromium alloy and its modulus of elasticity is closer to that of human bones, which can significantly minimise stress shielding and promote osteointegration and long term stable implantation.

The application advantages of medical titanium

The strength, toughness and biocompatibility of the weld area can be guaranteed with Ti-6Al-4V ELI welding wire in the medical weld. In particular, in high-risk applications such as spinal stents, orthopedic implants, dental implants, etc., the welds' quality directly influence the safety of the instruments. Our medical titanium welding wire is strictly controlled in terms of composition control, tensile performance, and ductility, which can meet the reliability requirements of long-term implanted devices.

(1) Medical grade full process quality control, in compliance with international standards
Our Ti-6Al-4V ELI welding wire is manufactured to the highest quality complying with ASTM F136 standard with full chemical composition, mechanical properties and quality test reports. The manufacturing process is rigorously managed in raw materials selection, vacuum melting, heat treatment, drawing and packaging to prevent contamination and over production of element to make certain the welding wire meets needs of medical device manufacturing and implant applications.

(2) Customizable medical specifications and cleaning packaging to meet the needs of instrument manufacturing
For medical device manufacturing customers, we offer customized wire diameters, hardness, annealing conditions, and packaging methods (vacuum/cleanroom packaging). Meanwhile, the batch traceability of materials, cleanliness testing and surface treatment suggestions can be supplied in accordance with customers' process requirements, ensuring the welding wire will not bring contamination during welding procedure and improving the pass rate of equipment.

(3) Comprehensive after-sales and technical support to assist customers in quickly passing certification
We provide customers with sample testing, process parameter recommendations, and assist in optimizing welding quality on their production lines. For customers who require product registration and certification, we can provide material proof, inspection reports, third-party testing support, and provide continuous after-sales service to ensure smooth product validation and mass production.

Q1: Can medical titanium welding wire be provided with clean packaging?
Okay. We are able to provide vacuum packaging, clean room packing and special anti-pollution packaging for the cleanliness demand of medical device manufacturing.

Q2: Is third party testing or material certification available?
That's right. We can support customer qualification and filing with third party testing reports, chemical composition certificates, mechanical properties reports and material batch traceability documents.

Q3: Is it possible to customize wire diameter and hardness as per customers' request?
Okay. We can do customized diameter, 0.5-6.0mm in diameter, and we can change the annealing condition and hardness based on customer's request for different welding process.
