Hi everyone—Zhen Liu here, your pure copper specialist at Cymber Metal. Pure copper plates and strips are the foundation of so many projects we do—flat, rolled material that’s soft enough to form but pure enough for top conductivity and heat transfer. Plates for busbars and heat sinks, strips for coils and gaskets—they’re simple but critical. We’ve rolled and machined tons of them for electrical panels, EV cooling, and industrial heat exchangers.
In 2026, with power demands rising and sustainability in focus, pure copper plates and strips are seeing steady use where maximum efficiency matters. This guide shares what we’ve learned in the shop: grades, applications, challenges, and tips to get flat, uniform material that performs.
Pure Copper Plate and Strip Grades Overview
Grade Comparison Table
| Grade | Purity | Oxygen Content | Key Strengths | Best Forms (Plate/Strip) | Conductivity (% IACS) | Relative Cost |
|---|---|---|---|---|---|---|
| C11000 (ETP) | 99.90% | ~200–400 ppm | Balanced cost, good ductility | General plates, wide strips | 100–101 | Low |
| C10200 (OF) | 99.95% | Oxygen-free | Excellent thermal/electrical | Precision strips, thin plates | 101 | Medium |
| C10100 (OFHC) | 99.99% | <5 ppm | Peak conductivity, no voids | High-end plates for vacuum/electronics | 101 | High |
Quick Tip: ETP (99.90%) for most plates and strips—cost-effective with great performance. Go OFHC for ultra-high conductivity in thin strips.
Key Applications of Pure Copper Plates and Strips
Pure copper plates and strips excel where conductivity, heat, or formability is key.
Electrical Power Distribution
Plates for busbars, strips for flexible connections—low resistance in high-current systems.
Thermal Management and Heat Exchangers
Plates as base for heat sinks, strips in coils—rapid heat spreading.
EV Battery and Charging Systems
Thin strips for flexible interconnects, plates for cooling bases.
Gaskets and Seals
Strips annealed for soft, conforming seals in flanges.
Roofing and Architectural (with note on brass alternative)
Plates for flashing—corrosion-free. (For more decorative golden look, many customers switch to brass plates/strips.)
Advantages of Pure Copper Plates and Strips
- Superior conductivity → Electrical and thermal—nothing beats pure copper.
- Excellent formability → Easy rolling, bending, stamping.
- Corrosion resistance → Long life in humid or mild chemical exposure.
- Ductility → Thin strips without cracking.
- Recyclability → Fully sustainable.
(Quick note: If you need higher strength with similar formability, brass plates and strips are a great step up—same rolling process but added durability.)
Challenges in Processing Pure Copper Plates and Strips
Common Issues
- Surface oxidation during rolling → Dull finish or scale.
- Edge cracking in thin strips → From overwork.
- Thickness variation → In wide plates.
Practical Shop Solutions
Engineering Experience: In our pure copper strip projects at Cymber Metal for EV flexible connectors, edge cracking showed up on thin 0.2 mm material. We adjusted rolling reduction and added intermediate annealing—got perfect edges with no cracks, and customers loved the uniform conductivity.
Pro Tip: Roll in controlled atmosphere when possible—keeps that bright copper surface ready for immediate use.
Design Considerations & Tips
- Thickness Range: Plates 3–50 mm; strips 0.1–3 mm.
- Width: Up to 1,000 mm for plates, narrower for strips.
- Temper: Annealed for forming, hard for strength.
- Edge Finish: Slit or milled—specify for application.
Tooling & Parameter Recommendations
- Rolling Mills: Precision for uniformity.
- Example Parameters (Rolling C11000 strip):
- Reduction: 10–20% per pass
- Temperature: Room for cold, light heat for thick
- Lubricant: Emulsion for clean surface
- Slitting: Sharp blades—burr-free edges.

- Gasket material
- Transformer foils
Cost & Sustainability Factors in 2026
Low to medium pricing with excellent recyclability—scrap plates/strips easily remelted.
