Copper Coated Wire: Flat, Round, Coiled, or Stranded for Industrial Uses

Copper Coated Steel Wire is a robust and versatile material that effectively combines the inherent strength of steel with the superior corrosion resistance of copper. The steel core delivers high tensile strength and durability, while the copper coating ensures excellent electrical conductivity and provides a protective barrier against rust and oxidation. This wire is extensively used in electrical applications, welding, grounding, and other industrial settings where both strength and conductivity are crucial. Its enhanced lifespan in harsh environments, thanks to the copper coating, makes it an ideal choice for outdoor and industrial uses.

Available Sections and Forms

• Sections: Copper Coated Steel Wire is available in both flat and round sections, catering to a variety of industrial needs.
• Forms: The wire can be supplied in coiled or stranded forms, making it suitable for hose reinforcement, shielding, and other specific applications.

Specifications

• Diameter: The wire is typically available in a diameter of 1.07mm, with a tolerance of +0.01 / -0.02mm, ensuring precision and consistency.
• Tensile Strength: The tensile strength of the wire ranges between 300 and 400 N/mm², providing reliable performance under various load conditions.
• Copper Coating: The copper coating is applied at a thickness of 25 g/m², offering optimal protection against corrosion while maintaining excellent conductivity.

Raw Materials

Steel Composition:

• Carbon (C): < 0.06%
• Silicon (Si): < 0.30%
• Manganese (Mn): 0.30 – 0.60%
• Phosphorus (P): < 0.035%
• Sulfur (S): < 0.035%
• Aluminum (Al): < 0.01%
• Chromium (Cr): < 0.2%
• Copper (Cu): < 0.3%
• Molybdenum (Mo): < 0.05%
• Nickel (Ni): < 0.25%

This material is typically annealed after the copper coating process to enhance its ductility and workability.

Packing Options

• Small Coils: Suitable for smaller projects or specific applications requiring more manageable wire quantities.
• Big Coils: Available in sizes up to 800 kg, including orbit coils with the following dimensions:
  Inner Diameter (ID): 400mm
