Working Principle: How Pure Copper Plates Are Manufactured

Pure Copper Plates and Sheets are produced through a precise manufacturing process:

Step 1: Raw Material Selection

High-purity copper cathodes or ingots (99% min purity) are selected based on the required grade (T1, T2, T3, C11000, etc.). Chemical composition is strictly controlled to meet international standards.

Step 2: Melting & Casting

The copper is melted in furnaces at controlled temperatures, then cast into slabs or billets. For oxygen-free grades (TU1, TU2, C10200), melting occurs in a controlled atmosphere to prevent oxidation.

Step 3: Hot Rolling

The cast slabs are heated and passed through rolling mills to reduce thickness. Hot rolling improves grain structure and mechanical properties while achieving initial dimensional requirements.

Step 4: Cold Rolling (for precise thickness)

For thinner gauges and better surface finish, the copper undergoes cold rolling to achieve the final thickness (1mm-3mm) with tight tolerances.

Step 5: Annealing (if required)

Depending on the desired hardness and formability, the copper may be annealed to achieve the required mechanical properties (elongation ≥35%, tensile strength 220-400 MPa).

Step 6: Surface Treatment

The plates are cleaned and polished to achieve a bright surface finish suitable for both industrial and decorative applications.

Step 7: Cutting & Sizing

Sheets are cut to required dimensions:

• Width: 20mm - 2500mm

• Length: 10mm - 12000mm

Step 8: Quality Inspection

Every plate undergoes rigorous testing:

• Chemical composition analysis (Cu ≥99%)

• Mechanical property testing (tensile, elongation)

• Dimensional inspection

• Surface quality check

Step 9: Packaging

Finished products are carefully packaged for export:

• Protective wrapping to prevent surface damage

• Moisture protection for sea transport

  • Protective wrapping to prevent surface scratches

  • Moisture-proof materials for sea transport

  • Secure bundling with steel strips

  • Edge protectors to prevent damage

  • Suitable for container or bulk vessel shipping

    Secure bundling for safe handling

    FAQ (Frequently Asked Questions)

    Q1: What is the difference between T1, T2, and T3 copper?

    A:

    • T1 Copper: Highest purity (99.97% min), oxygen-free, best conductivity and ductility. Used for critical electrical applications, vacuum devices, and high-performance electronics.

    • T2 Copper: High purity (99.90% min), excellent balance of properties and cost. Most common grade for general industrial and electrical applications (equivalent to C11000).

    • T3 Copper: Standard purity (99.70% min), good for general fabrication where extreme purity isn't required. More economical for decorative and non-critical applications.

    Choose T1 for maximum performance, T2 for standard industrial use, T3 for cost-sensitive decorative projects.
