product key technologies
Raw materials, melting, and surface treatment
Using high-purity sponge titanium with a purity of ≥ 99.9% (industrial pure titanium TA1/TA2) or customized alloys (such as Ti-6Al-4V, nickel titanium alloys), nuclear industry grade neutron sensitive elements such as boron and cadmium need to be controlled.
Vacuum consumable electric arc furnace (vacuum degree ≤ 10 ⁻ ³ Pa) melts 2-3 times to eliminate impurity segregation, with ingot diameter of 50-150mm.
Medical grade: Sandblasting and acid washing enhance bone integration ability, and surface roughness promotes cell adhesion.
Industrial grade: Anodizing forms a colored corrosion-resistant film, and micro arc oxidation generates a ceramic layer (hardness increased by 5 times); Laser texturing technology enhances the conductivity and reliability of electronic components.
Plastic Forming and Functional Characteristics
Hot processing: After the ingot is uniformly annealed at 900-1050 ℃, it is opened to a diameter of 5-10mm through hot forging (750-950 ℃) or hot rolling (800-900 ℃).
Cold drawing: Multi pass drawing at room temperature (single deformation ≤ 15%), combined with intermediate annealing (600-800 ℃) to eliminate work hardening, the finished wire diameter can reach 0.02mm; ultra-fine wire (≤ 0.05mm) requires diamond molds and special lubricants (lime milk/animal oil).
Biocompatibility: The surface TiO ₂ oxide layer promotes bone cell adhesion, and the 10-year survival rate of orthopedic implants is>95%; Non magnetic compatible MRI examination.
Shape memory: Nickel titanium alloy wire triggers deformation at body temperature, simplifying minimally invasive surgical procedures.

Titanium wire, with its groundbreaking mechanical properties and environmental stability, has become a key material link connecting cutting-edge technology and industrial upgrading. From the intelligent deformation of 0.1mm nickel titanium alloy wire in vascular stents to the breakthrough of welding repair technology for TC4 alloy wire in aviation engines, titanium wire continues to redefine the application boundaries of materials. Its lightweight, corrosion-resistant, and biocompatible characteristics are rewriting industry standards for medical implants, high-end equipment, and energy technology.
The current technological bottleneck is focused on the precision and cost control of ultra-fine wire processing, which requires deep collaboration between materials science, precision manufacturing, and digital technology. With the development of electrolytic wire production and 3D printing composite technology, titanium wire will unleash greater potential in emerging fields such as micro robot driving and space in orbit manufacturing.
Titanium wire is not only an industrial component, but also has the potential to become the "nerve and muscle" of intelligent systems. When the material properties are deeply integrated with artificial intelligence and biotechnology, titanium wire may evolve from a functional carrier to an active material with environmental responsiveness, ushering in a new round of technological revolution.
