Explore our precision-manufactured titanium mill products, drawn, rolled, and forged to rigorous ASTM/ASME standards for high-stress industrial applications.
Understanding the dislocation physics, crystal deformation mechanisms, microstructural grain alignment, and intermediate vacuum annealing protocols in cold-drawn titanium wire manufacturing.
Alpha-phase titanium possesses a Hexagonal Close-Packed (HCP) lattice structure, offering restricted active slip systems at room temperature. Cold drawing forces dislocation movement along prismatic {10-10} and pyramidal {10-11} planes, accompanied by mechanical twinning. This work-hardening mechanism increases tensile yield strength by up to 45% compared to hot-rolled wire rods.
Our cold-drawing process utilizes custom polycrystalline diamond (PCD) and tungsten carbide dies featuring optimized approach angles (10° to 14°) and bearing lengths. By limiting cross-sectional area reduction to 10%–15% per pass, we eliminate internal central bursting (chevrons) and maintain strict roundness/ovality tolerances within ±0.005 mm.
Titanium reacts aggressively with interstitial oxygen, nitrogen, and hydrogen at elevated temperatures. ProX Metal conducts intermediate vacuum annealing in cold-wall vacuum furnaces under high vacuum (< 10⁻⁴ Torr) at temperatures ranging from 650°C to 750°C. This restores elongation ductility without creating a brittle alpha-case surface layer.
Analyzing the expansion of titanium wire applications across next-generation additive manufacturing, medical implantology, aerospace fast-response supply chains, and green hydrogen infrastructure.
Wire Arc Additive Manufacturing (WAAM) and Directed Energy Deposition (DED) demand high-purity, ultra-clean surface wire feedstock. Cold-drawn Ti-6Al-4V Grade 5 wire provides consistent feed rates, zero micro-porosity inclusions, and uniform chemical homogeneity required for printing large-scale aerospace structural components.
Cold-drawn Ti-6Al-4V ELI (Grade 23) and pure titanium Grade 1 micro-wires (down to 0.05 mm diameter) are increasingly specified for bone staples, suture wires, dental pins, and vascular stents. Excellent biocompatibility, non-magnetic properties, and high fatigue resistance ensure optimal long-term clinical safety.
The global transition toward green hydrogen requires titanium wire mesh electrodes capable of resisting severe acidic oxidation within Proton Exchange Membrane (PEM) water electrolyzers. Cold-drawn Grade 1 titanium fine wire woven meshes coated with platinum or iridium provide exceptional service life and low contact resistance.
In deep-sea oil extraction and chlor-alkali chemical processing, cold-drawn Grade 7 (Ti-0.2Pd) and Grade 12 (Ti-0.3Mo-0.8Ni) wires deliver unmatched resistance to crevice corrosion and reducing acids, preventing costly subsea cable armor failures and chemical reactor leakage.

Founded in 2001, ProX Metal operates a fully integrated titanium production chain from raw sponge melting to ultra-fine wire cold drawing, backed by ISO 9001:2015 accreditation and 14 national patents.
Our production facility incorporates multi-pass continuous cold drawing units, high-speed centerless grinding lines, continuous bright vacuum annealing furnaces, and eddy-current surface defect detection systems, ensuring zero micro-fractures across millions of meters of titanium wire.
Every batch of cold-drawn titanium wire undergoes positive material identification (PMI XRF), laser micrometer roundness checking, tensile testing, optical metallographic grain size determination, and EN 10204 3.1 chemical analysis certification.
To prevent wire tangling during automated robotic welding or high-speed knitting, we offer precision layer-winding on BS300, K350, DIN200 spools, and custom coil packaging with desiccants and protective argon-shielded vacuum bagging.
In addition to high-precision cold-drawn titanium wires, ProX Metal manufactures comprehensive titanium plates, bars, seamless/welded tubes, capillary pipes, and forgings.

Cold-drawn titanium wire exhibits significantly superior surface finish (Ra < 0.4 µm), tighter diameter tolerances (down to ±0.005 mm), and elevated tensile yield strength resulting from work hardening. Unlike hot-rolled wire rod which exhibits surface oxide scale (alpha-case layer), cold-drawn wire offers clean, uniform microstructures ideal for high-speed automated welding, medical devices, and precision springs.
We supply titanium cold-drawn wire in diameters ranging from ultra-fine 0.05 mm up to 6.0 mm. Spooling configurations include BS300, K350, DIN200 plastic/metal spools for robotic welding machines, as well as catch-weight coils, straight cut lengths (1000 mm to 3000 mm), and customized carrier spools.
Titanium readily absorbs hydrogen gas above 300°C, forming brittle hydride precipitates. We prevent hydrogen pick-up by implementing non-acid mechanical scalping, using non-reactive synthetic drawing lubricants, and executing all intermediate annealing stages inside ultra-high vacuum furnaces (< 10⁻⁴ Torr) with continuous residual gas monitoring.
Yes. Our Grade 5 (Ti-6Al-4V) and Grade 2 cold-drawn titanium wires strictly conform to AWS A5.16 welding wire standards. Each spool features continuous cast and helix control to guarantee smooth wire feeding through robotic torch liners without binding or micro-porosity defects in the 3D-printed metal matrix.
Grade 7 (Ti-0.2Pd) is the optimal material grade for reducing media such as hydrochloric, sulfuric, and phosphoric acids due to the catalytic passivation effect of palladium. For high-temperature chlor-alkali brine, Grade 12 (Ti-0.3Mo-0.8Ni) provides an economical corrosion-resistant alternative.
All shipments are accompanied by comprehensive EN 10204 3.1 Material Test Certificates (MTC) detailing complete heat number traceability, ladle chemical analysis, room-temperature tensile test results (tensile strength, yield point, elongation), dimensional inspection logs, and NDT defect test clearance reports.
