copper-plated iron wire


          

Product Description:
This copper-plated iron wire is made of high-quality low-carbon steel as the base material. Adopting advanced cyanide-free electroplating/electroless plating technology, a dense copper layer is evenly coated on the surface of the iron wire. It combines the high strength and toughness of steel with the conductivity, corrosion resistance and weldability of copper.With precise tolerance and strong coating adhesion, it is not easy to peel off or oxidize. Widely suitable for electrical, industrial manufacturing, wire mesh processing and other fields, it is a cost-effective metal wire solution.

2. Core Advantages

Advantage FeaturesTechnical SupportPractical Value
Excellent ConductivityCopper layer purity ≥ 99.5%, uniform and controllable coating thicknessMeets medium and low voltage electrical transmission needs, replaces part of pure copper wire, and reduces costs
Superior Corrosion ResistanceDense copper layer isolates air and moisture; customizable galvanized + copper-plated double-layer protectionExtends service life by 3-5 times in outdoor/humid environments and reduces maintenance costs
High Coating AdhesionPre-nickel plating base + high-temperature curing processNo peeling or bulging during bending, stretching and stranding, suitable for complex processing
Good WeldabilityCopper layer has good affinity with solder, and welding joints are firmDirect welding without additional treatment, improving electrical assembly efficiency
High Toughness & UnbreakableLow-carbon steel base material with tensile strength ≥ 450MPaWithstands mechanical stretching, winding, weaving and other processing, not easy to deform or break

4. Application Fields

4.1 Electrical & Communication Field

  • Conductors for wires and cables, grounding wires, signal transmission wire cores

  • Auxiliary wires for transformers and motor windings

  • Base materials for electrical equipment terminals and connectors

4.2 Industrial Manufacturing Field

  • Reinforcing framework for rubber hoses (high-pressure hoses, hydraulic oil pipes). The copper layer has strong adhesion to rubber, improving the pressure resistance of hoses.

  • Wire materials for steel wire brushes and polishing brushes, featuring good wear resistance and elasticity

  • Weaving of metal meshes, filter meshes and protective meshes, which are rust-proof and durable

4.3 Construction & Decoration Field

  • Supporting wires for ceiling keels, fixing wires for curtain walls

  • Wire materials for handicrafts and flower arrangement modeling, easy to bend and shape, and not easy to rust

4.4 Other Customized Scenarios

  • Special wire for bundling (replaces galvanized iron wire, more beautiful and rust-proof)

  • Weaving wire for fishing gear and pet cages

5. Production Process

Raw Material Selection → Surface Degreasing & Derusting → Pre-nickel Plating → Precision Copper Plating → High-temperature Curing → Precision Wire Drawing → Quality Inspection → Finished Product Packaging✅ Environmental Protection Process: Adopts cyanide-free copper plating technology, complies with RoHS and REACH environmental standards, and can be exported to European and American markets.

6. Packaging & Transportation

  • Regular Packaging: Lined with moisture-proof wax paper/PE film, bundled with kraft paper/sacking cloth on the outer layer. Customizable bundle weight from 5kg to 50kg.

  • Moisture & Rust Prevention: Sealed packaging + desiccant to prevent oxidation and discoloration during transportation and storage.

  • Transportation Methods: Supports sea/land/air transportation, and can provide palletized reinforced packaging to meet the requirements of foreign trade container transportation.
