Womic Copper is proud to offer premium-quality copper tube solutions based on T2 and T3 grades, manufactured under the national standard GB/T 5231-2012. Our copper tubes are engineered for high precision, excellent electrical and thermal conductivity, and reliable corrosion resistance — serving critical roles across power systems, new energy, electronics, aerospace, and precision engineering industries.

1. Material Composition & Performance

T2 Copper Tube (Equivalent to ASTM C11000):

- Purity: ≥ 99.90% Cu
- Electrical Conductivity: ≥ 58 MS/m (IACS 100%)
- Thermal Conductivity: ≥ 390 W/(m·K)
- Hardness: HBW 40-75 depending on temper
- Magnetic Permeability: ≤ 1.003 (non-magnetic)

T3 Copper Tube:

- Purity: ≥ 99.70% Cu
- Electrical Conductivity: ≥ 50 MS/m
- Cost Efficiency: ~5% lower than T2
- Good Processability: Suitable for bending, stamping, and surface treatment

2. Production Process

Womic Copper uses state-of-the-art equipment and refined production techniques to ensure consistent quality:
1. Raw Material Selection
2. Melting & Casting
3. Extrusion & Drawing
4. Annealing
5. Surface Finishing
6. Inspection

3. Application Scenarios

T2 Copper Tube:

- Electric Power: Transformer windings, high-voltage busbars
- New Energy: Battery module connectors, CTP cell interconnects
- Precision Engineering: Semiconductor equipment grounding, aerospace landing gear sleeves
- Medical: CT machine rotating connectors (FDA biocompatibility certified)

T3 Copper Tube:

- Automotive: Spark plug electrodes, fuel system components
- Construction: Residential electrical wiring, decorative pipework
- HVAC: Air conditioner compressors, heat exchanger tubing

4. Packaging Requirements

To ensure the integrity and cleanliness of copper tubes during transportation and storage:
- Inner Packing: Each tube is capped and sealed with corrosion-resistant PE film
- Outer Packing: Bundled with waterproof kraft paper and anti-collision foam, fixed in wooden crates
- Labeling: Each bundle marked with grade, lot number, dimensions, and heat number

5. Transportation Modes

Womic Copper provides flexible and secure delivery solutions:
- Domestic Delivery: Truck + rail transport for major project sites
- International Export: Sea freight via Tianjin and Shanghai ports
- Container Load Options:
• 20GP: Suitable for < 25MT of small-diameter coils
• 40HQ: For bulk order of long straight tubes
- Securing Methods: Steel straps, anti-slip mats, and container bracing to prevent damage in transit

6. Production Advantages of Womic Copper- Fully Integrated Supply Chain: From copper ingot casting to finished tube extrusion

- Precision Engineering: CNC-controlled rolling and cutting systems
- High Conductivity Guarantee: 100% IACS for T2 tubes, certified by third-party labs
