Pure Copper Rod (C11000) - Premium Quality for Industrial & Commercial Applications

Product Overview

Our pure copper rod (also known as red copper rod) is a high-performance metal product crafted from premium C11000 copper, renowned for its exceptional electrical conductivity, thermal conductivity, and corrosion resistance. With strict adherence to international quality standards, this product offers reliable performance across a wide range of industrial, commercial, and precision engineering applications.

Key Material Properties

- Chemical Composition: Copper (Cu) ≥ 99.90%, Oxygen (O) ≤ 0.04%, with trace amounts of impurities (Fe, Pb, Zn, etc.) strictly controlled within industry limits.
- Mechanical Performance: Tensile strength ≥ 220 MPa, Yield strength ≥ 70 MPa, Elongation (after fracture) ≥ 30%, Hardness (HB) ≥ 65.
- Core Characteristics:
- Excellent electrical conductivity (IACS ≥ 98%): Ideal for electrical and electronic components requiring efficient current transmission.
- Superior thermal conductivity (≥ 390 W/(m·K)): Ensures rapid heat dissipation in high-temperature environments.
- Outstanding corrosion resistance: Resists oxidation and chemical erosion in both dry and moderately humid conditions, maintaining structural integrity over long-term use.
- High ductility and malleability: Easy to cut, bend, weld, and machine into custom shapes without compromising material performance.
- Non-magnetic property: Suitable for applications sensitive to magnetic interference.

Specifications & Customization

Standard Sizes

- Shape: Round rod (most common), square rod, hexagonal rod (customizable).
- Diameter Range: Round rod: 3mm - 100mm; Square rod: 5mm×5mm - 80mm×80mm; Hexagonal rod: 6mm - 60mm (across flats).
- Length: 1m, 2m, 3m (standard), or customized lengths up to 6m as per customer requirements.

Customization Options

We offer tailored solutions for specific requirements, including:

- Custom diameters, lengths, and cross-sectional shapes.
- Special heat treatment (annealing, quenching) to adjust hardness and ductility.
- Precision machining (threading, grooving, cutting) for ready-to-install components.

Applications

Our pure copper rod is widely utilized in various sectors due to its versatile performance:

- Electrical & Electronics: Electrical wires, cables, busbars, terminal blocks, transformer windings, circuit breaker components.
- Mechanical Engineering: Hydraulic and pneumatic fittings, valves, bearings, fasteners (bolts, nuts), precision machine parts.
- Heat Exchangers & Cooling Systems: Radiator cores, heat pipe materials, condenser tubes, solar water heater components.
- Construction & Architecture: Decorative hardware, plumbing fixtures, roofing materials, architectural accents.
- Automotive & Aerospace: Electrical systems in vehicles, aircraft wiring harnesses, heat dissipation parts.
- Medical Equipment: Surgical instruments, diagnostic device components (requiring high purity and corrosion resistance).

Quality Assurance

- Manufactured in ISO 9001:2015 certified facilities, with strict quality control throughout the production process (raw material inspection, casting, rolling, drawing, heat treatment, finished product testing).
- Each batch of products undergoes comprehensive testing, including chemical composition analysis, mechanical property testing (tensile, hardness, elongation), and dimensional accuracy inspection (using precision calipers and micrometers).
- Compliant with international standards such as ASTM B42 (USA), BS 1432 (UK), and GB/T 4423 (China) to ensure global compatibility.

Packaging & Shipping

- Packaging: Products are wrapped in moisture-proof paper or plastic film, then packed in wooden crates or steel bundles to prevent damage during transportation. For small batches, custom packaging (cartons, bags) is available.
- Shipping: Worldwide delivery via sea, air, or express (DHL, FedEx, UPS). We work with reliable logistics partners to ensure on-time delivery, and provide complete shipping documents (commercial invoice, packing list, certificate of quality, customs declaration).
