Red copper rod

Product Overview

Our Red Copper Rod (also known as Pure Copper Rod) is a premium solid metal bar engineered from high-purity copper (Cu+Ag content ≥ 99.90%) through advanced processes including fire refining, continuous casting, and precision drawing. Characterized by its distinctive reddish-purple luster, this rod integrates exceptional electrical conductivity, thermal conductivity, and malleability—outperforming most alloy rods in scenarios demanding efficient energy transfer and precise processing. Available in both round and shaped profiles, as well as varied hardness states, our Red Copper Rod caters to diverse needs from electrical components to industrial machinery, serving as a reliable core material across high-tech and traditional manufacturing sectors.

Core Features & Advantages

• Ultra-High Purity & Structural Integrity: Crafted with strict impurity control (total impurities ≤ 0.1% for T2 grade), our rods feature dense microstructure free of pores, sand holes, or looseness. Advanced rare earth microalloying purification technology further reduces harmful impurities to below 400ppm, ensuring stable performance in critical applications like precision electrodes.
• Exceptional Electrical & Thermal Conductivity: With electrical conductivity reaching ≥ 98% IACS (even up to 100% IACS for high-grade variants) and thermal conductivity of 390 W/(m·K), it ranks second only to silver among common metals. This makes it ideal for current-carrying components and heat-dissipating parts where energy efficiency is paramount.
• Superior Malleability & Processability: The rod exhibits excellent ductility (elongation ≥ 30% in annealed state) and can be easily processed via hot/cold pressing, forging, cutting, and welding without cracking. Its non-directional structure after heat treatment enables precise machining, suitable for fine engraving and high-precision component manufacturing.
• Reliable Corrosion Resistance: A natural oxide film forms on the surface to resist corrosion in atmospheric environments, seawater, and non-oxidizing acids (e.g., dilute sulfuric acid) as well as organic acids like acetic acid. This ensures long-term durability in both industrial and outdoor applications, with a service life exceeding 30 years under standard conditions.
• Diverse Customization Options: We offer comprehensive customization to match specific requirements:
  • Profiles: Round rods (diameter 5mm - 200mm) and shaped rods (square, hexagonal, rectangular).
  • Production Methods: Extruded rods (for large diameters) and drawn rods (for high precision).
  • Hardness States: Soft (annealed), half-hard, and hard states to accommodate flexible bending or structural load-bearing needs.
  • Grades: T1 (99.95% Cu+Ag), T2 (99.90% Cu+Ag), TU1 无氧铜，and customized special copper variants.

Technical Specifications

Typical Applications

Leveraging its versatile performance, our Red Copper Rod is widely used across key industries:

• Electrical & Electronics: Manufacturing of electrical brushes, wire/cable cores, PCB current-carrying bars, and precision electrodes for EDM (electrical discharge machining)—benefiting from high conductivity and machining precision.
• Mechanical Engineering: Production of valves, fittings, and structural components in pumps and compressors—utilizing its malleability and corrosion resistance.
• Construction & Decoration: Architectural hardware (handles, railings) and decorative elements—showcasing its natural reddish luster and weather resistance.
• Transportation: Heat-dissipating parts in automotive radiatorsand high-speed rail electrical components—combining thermal conductivity and structural stability.
• Chemical Industry: Reaction vessel linings and fluid transport pipes—resisting corrosion from organic acids and alkaline solutions.

Quality Assurance

Our Red Copper Rod is produced in ISO 9001-certified facilities, adhering to the GB/T 38470-2023 standard for copper materials and implementing a full-process quality control system. Each batch undergoes rigorous testing:

• Chemical composition analysis via X-ray fluorescence spectrometry to ensure purity compliance;
• Dimensional inspection with laser gauges for precision control;
• Conductivity testing using Kelvin bridges;
• Mechanical performance evaluation (tensile strength, elongation) via universal testing machines;
• Ultrasonic flaw detection to eliminate internal defects like pores or inclusions.

We provide pre-sales technical consultation (material grade selection, process optimization) and after-sales support, including custom machining guidance. Detailed material certificates and test reports are supplied with each order to ensure traceability.
