2. Manufacturing & Processing Workflow
Our production process combines strict quality control and advanced processing to ensure every plate meets international electrical standards:
Raw Material SelectionWe source only high-grade electrolytic copper, brass ingots, and 1060 aluminum billets, with full chemical composition testing to eliminate impurities that could degrade conductivity or performance.
Precision Rolling & FormingUsing hot and cold rolling mills, we reduce the material to your specified thickness with tight tolerances (±0.02mm). For large-format brass plates, we use wide-plate rolling technology to ensure flatness and consistency across the entire sheet.
Tempering & Heat TreatmentBased on your application, we perform annealing, hardening, or stress-relief processes to adjust the material's ductility, hardness, and mechanical stability, critical for transformer winding and assembly.
Surface Finishing & Quality InspectionAll plates undergo cleaning, deburring, and optional surface treatments (e.g., anti-tarnish coating for copper). We conduct 100% visual inspection, conductivity testing, and dimensional checks to guarantee compliance with your specifications.
Custom Fabrication (Optional)We offer secondary processing services including cutting, stamping, bending, drilling, and CNC machining to deliver ready-to-use parts for your transformer production line.
3. Advantages & Disadvantages of Our Materials
✅ Copper Plate (C1100)
Advantages
Highest Electrical Conductivity: 100% IACS conductivity, far superior to aluminum, minimizing energy loss and heat generation in transformers.
Superior Thermal Management: Excellent heat dissipation reduces hotspots, extending transformer lifespan.
Long-Term Durability: High corrosion and oxidation resistance, even in harsh industrial environments.
Mechanical Strength: High tensile strength and ductility, ideal for tight winding and complex transformer designs.
Disadvantages
Higher material cost compared to brass or aluminum.
Heavier weight, which may impact overall transformer design and shipping costs.
✅ Brass Plate (C2680)
Advantages
Balanced combination of conductivity, strength, and corrosion resistance.
Excellent formability, suitable for stamping and forming into custom busbars or components.
Lower cost than pure copper, offering a cost-effective alternative for non-critical conductive parts.
Disadvantages
Lower electrical conductivity than pure copper, making it less ideal for high-efficiency core windings.
✅ Aluminum Plate (1060)
Advantages
Lightweight and cost-effective, ideal for large-scale or budget-focused transformer projects.
Good thermal conductivity, suitable for heat sinks and auxiliary components.
Easy to machine and weld, supporting fast production.
Disadvantages
Lower conductivity than copper, requiring larger cross-sectional areas to carry the same current.
Higher tendency to form oxide layers, which can impact long-term connection reliability.
4. Frequently Asked Questions (FAQ)
Q1: Are your copper plates suitable for transformer winding applications?
A: Yes! Our C1100 copper plates have a purity of ≥99.95% and are specifically engineered for transformer windings, busbars, and conductive components. The low resistivity ensures minimal power loss, while customizable temper options match your winding and assembly requirements.
Q2: Can you provide custom sizes and tolerances beyond the listed specifications?
A: Absolutely. We offer fully customized dimensions for all three materials, including non-standard widths, thicknesses, and cut-to-size shapes. Simply share your drawings or specifications, and our engineering team will provide a tailored solution.
Q3: What quality certifications do your products comply with?
A: Our plates meet international standards including ASTM B152 (copper), ASTM B19 (brass), and ASTM B209 (aluminum). We also provide full material test reports (MTRs) with every order for traceability and compliance.
Q4: How do you ensure flatness and surface quality for large-format plates?
A: Our wide-plate rolling process includes precision leveling and stress-relief treatment to eliminate warping. Every plate is inspected for surface defects, scratches, and flatness using automated gauging equipment.
Q5: What is your lead time for bulk orders?
A: Standard lead time is 15–25 days for production, depending on order quantity and customization requirements. We also offer expedited services for urgent projects upon request.
