GR1 titanium ultrafine wire is manufactured from high-purity titanium (Ti-99.6%) through precision cold drawing and annealing processes, meeting ASTM B863 and ISO 5832-2 standards. It combines corrosion resistance, biocompatibility, and mechanical properties. The product diameter ranges from 0.05mm to 10.0mm, with the 0.05mm-0.5mm ultrafine segment produced using diamond dies and multi-pass cold drawing technology, achieving a surface roughness ≤0.2μm and a breakage rate ≤0.3%. Tolerance accuracy reaches ±0.002mm (0.05mm-0.5mm). Standard coils weighing 1kg to 50kg are available, along with custom specifications. The surface undergoes electrolytic polishing, pickling, or passivation treatment to meet diverse application requirements.

This product can be used in the medical field to manufacture sutures with a tensile strength of ≥480 MPa and a diameter of 0.05mm–0.1mm, certified by ISO 10993, or as orthodontic archwires with a diameter of 0.2mm–0.5mm. In the electronics sector, 0.025mm wire material is employed for 5nm chip bonding, enhancing thermal conductivity by 50% while reducing costs by 70%. In aerospace applications, 0.8mm–2.0mm wire material boasts a density of only 45% that of steel, maintaining a strength of 716 MPa at 480°C after annealing at 650°C. The production process involves multi-pass cold drawing (single-pass reduction ≤15%), liquid nitrogen cooling, and diamond molds, combined with intelligent annealing at 650±10°C and HF:HNO₃ electrolytic polishing, ensuring uniform diameter and surface smoothness, with oxygen content ≤800 ppm.
The product strictly controls components such as O≤0.18% and Fe≤0.20%, with a tensile strength of 345-515MPa and an elongation rate of ≥18%. The export packaging includes a material certificate and supports DAP and FOB transportation. Its 0.05mm ultra-fine specification has a breakage rate of less than 94% industry standard, with customizable straightness, coating, and coil diameter. It is certified by ISO 9001, FDA, and others, with a minimum order quantity of 1kg and standard orders delivered within 7-15 days. Typical applications include European cardiac pacemaker electrodes, domestic chip packaging, and U.S. drone skeletons.
