Zirconium Copper Wire – High-Temperature Conductive Wire for Industrial Applications
XI AN LINHUI IMPORT AND EXPORT Co., LTD. manufactures premium Zirconium Copper Wire (UNS C15000) through two specialized factories operating 30 titanium and non-ferrous metal production lines. With 21 years of manufacturing expertise, we produce 800 tons annually under ISO/SGS/TÜV quality systems.
Our item contains 0.13–0.20% Zr, keeping up 93–95% IACS conductivity whereas standing up to warm softening up to 525°C. This understands basic disappointments in resistance welding terminals, EV engine commutators, and high-current switchgear where standard copper anneals over 200°C. We provide by means of DHL, FedEx, discuss, or ocean cargo with stock orders shipping in 3–7 days.
Key Features & Benefits
Superior Warm Stability: Retains mechanical quality at 500°C+ working temperatures, avoiding terminal misshapening amid resistance welding cycles.
Optimized Conductivity-Strength Balance: Achieves 350–550 MPa ductile quality without relinquishing electrical performance—ideal for high-amperage applications requiring negligible resistive loss.
Extended Benefit Life: Reduces anode staying on galvanized steel by 60–80% compared to unadulterated copper, bringing down consumable substitution recurrence in car generation lines.

Manufacturing Process
Step 1: Vacuum Casting
Oxygen-free copper liquefied with high-purity zirconium beneath vacuum to avoid oxidation. This guarantees uniform Zr dissemination and <10 ppm oxygen content.
Step 2: Hot Rolling & Cold Drawing
Billets hot-rolled to intermediate diameters, then multi-pass cold drawn with controlled reduction rates. This process generates fine Zr precipitates at grain boundaries for thermal stability.
Step 3: Aging Treatment
Wire aged at 400–450°C for controlled precipitation hardening. This balances conductivity retention with peak hardness for your specific application requirements.
Applications
Resistance Welding Electrodes: Cold-headed into cap tips for automotive body assembly lines. Withstands 1,500+ spot welds on galvanized steel without sticking.
EV Motor Commutators: Drawn into trapezoidal segments for high-RPM traction motors. Prevents bar deformation under centrifugal forces exceeding 15,000g.
Circuit Breaker Components: Flexible connectors in high-voltage switchgear maintain spring properties through 10,000+ thermal cycling events.
Semiconductor Lead Frames: Zirconium Copper Wire bonding substrates requiring both thermal dissipation and mechanical rigidity during plastic encapsulation processes.

FAQ
Q: Can you supply C15000 wire with silver plating?
A: Yes. We offer electrolytic silver plating (3–5 μm thickness) for improved solderability and oxidation resistance in muggy environments.
Q: What mood is best for cold heading welding caps?
A: Half Difficult (H02) with 15–20% stretching permits pass on shaping without breaking, taken after by your in-house maturing if needed.
Q: How does estimating compare to unadulterated copper?
A: Anticipate 20–35% premium due to vacuum casting necessities and zirconium fabric costs—offset by 3–5× longer anode benefit life.
Q: Is oxygen-free review accessible?
A: All our product uses oxygen-free copper base (<10 ppm O₂) to prevent Zr oxide formation and ensure brazing compatibility.
