Copper Wire is a conductive metal wire made of high-purity electrolytic copper (Cu≥99.9%) by wire drawing process. According to different uses, can be divided into bare copper wire, tinned copper wire, enamelled wire and other types, widely used in power transmission, electronic connection, motor winding and industrial manufacturing and other fields. Because of its high conductivity, excellent ductility and cost advantages, copper wire has become an irreplaceable basic material in electrical engineering.
Copper wire is the core material of the electrical and electronics industry due to its excellent electrical conductivity, processing flexibility and cost effectiveness. ZMSH meets customers' diverse requirements for high performance copper wire through strict quality control and customized services.

1. Electrical conductivity: the resistivity is 1.68×10⁻⁸Ω·m (20℃), second only to silver and better than aluminum (2.82×10⁻⁸Ω·m).
2. Thermal conductivity: Thermal conductivity 401W/(m·K), suitable for heat dissipation applications.
3. Mechanical properties:
· Tensile strength 200-400MPa (varies with wire diameter and heat treatment).
· Elongation 15-40%, easy to process into thin lines (up to 0.01mm).
4. Corrosion resistance: bare copper is easy to oxidize, tin plating or silver plating can improve corrosion resistance.
5. Temperature range: long-term working temperature -40℃~150℃ (enameled wire can reach 180℃).
(1) Power transmission
· Overhead wire: Hard copper wire (such as ASTM B1 standard) for high-voltage transmission.
· Cable core: soft copper wire (e.g. IEC 60228 Class 5) for power cables.
(2) Electronic connection
·PCB lead bonding: 0.025-0.5mm diameter gold-plated copper wire for chip packaging.
Wiring harnesses and connectors: wires in automobiles and home appliances (such as UL1007 certified wires).
(3) Motor and transformer
· Enamelled wire: polyester/polyurethane coating for motor winding (withstand voltage >1kV).
· Electromagnetic coils: inductors such as high-frequency transformers and relays.
(4) Industrial manufacturing
· Welding material: tinned copper wire for electronic welding (Sn content 1-3%).
· Metal braid: anti-interference structure such as shielding net and grounding wire.
1. Q: What is copper wire used for?
A: Copper wire is primarily used for electrical wiring, electronics, and motors due to its high conductivity and flexibility.
2. Q: Why is copper used for electrical wiring instead of aluminum?
A: Copper has lower resistance and better durability than aluminum, making it more efficient for power transmission.
