Component Specifications

Definition
A precision-engineered copper tubing component designed specifically for induction coil applications, where it serves as the primary conductor for alternating electrical currents. This component is characterized by its high electrical conductivity, thermal dissipation properties, and structural integrity under electromagnetic forces. It is typically manufactured through extrusion or drawing processes to achieve precise dimensional tolerances and smooth surface finishes that minimize electrical resistance and eddy current losses.
Working Principle
Operates on electromagnetic induction principles where alternating current passing through the copper tubing generates a rapidly alternating magnetic field. This field induces eddy currents in conductive materials placed within the coil's influence, generating heat through Joule heating. The tubing's design maximizes current density while minimizing resistive losses and thermal buildup through efficient heat dissipation.
Materials
High-purity oxygen-free copper (C10100/C10200) with minimum 99.95% copper content, often with silver plating or tin coating for enhanced surface conductivity and oxidation resistance. May include trace elements like phosphorus for deoxidation.
Technical Parameters
  • Bend Radius 3×OD minimum
  • Outer Diameter 3-50 mm
  • Wall Thickness 0.5-5 mm
  • Tensile Strength 200-350 MPa
  • Surface Roughness Ra ≤ 0.8 μm
  • Electrical Conductivity ≥100% IACS
  • Maximum Operating Temperature 200°C
Standards
ISO 9001, ASTM B75, IEC 60228, DIN 40500

Frequently Asked Questions

Why is copper specifically used for induction coil tubing?

Copper offers the best combination of high electrical conductivity (second only to silver), excellent thermal conductivity, good mechanical workability, and reasonable cost, making it ideal for efficient energy transfer in induction applications.

How does wall thickness affect performance?

Thicker walls increase mechanical strength and current-carrying capacity but also increase material cost and weight. Thinner walls reduce skin effect losses at high frequencies but may compromise structural integrity. Optimal thickness balances electrical, thermal, and mechanical requirements.

What maintenance does copper conductor tubing require?

Regular inspection for oxidation, mechanical damage, and connection integrity; periodic cleaning to maintain surface conductivity; monitoring for signs of overheating or deformation; and replacement when conductivity degrades beyond acceptable limits.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
