Kupferstab

Hochreine Kupferstäbe, die für überlegene Leitfähigkeit, mechanische Haltbarkeit und vielseitige Anwendungen in der Drahtziehung, elektrischen Komponenten und erneuerbaren Energiesystemen entwickelt wurden. Hergestellt nach strengen internationalen Standards.

Product Introduction: ZTT’s copper rods are produced using high-purity cathode copper (≥99.99%) through advanced up-draw continuous casting technology. Available in soft (R), hard (Y), and oxygen-free variants, they serve as core materials for wires, cables, and electrical conductors.

Product Advantages:

Exceptional Conductivity: Ultra-low electrical resistivity (0.017241 Ω•mm²/m for TR type) ensures minimal energy loss.High Mechanical Strength: Tensile strength up to 420 N/mm² (TY type) for reliable performance in demanding environments.Precision Manufacturing: Tight dimensional tolerances (e.g., ±0.002mm for Ø0.20–0.025mm) guarantee consistency.Corrosion & Oxidation Resistance: Oxygen-free rods (TU1/TU2) resist degradation, extending product lifespan.
