CU9743 High-Precision Copper Strip (C11000)

High-Precision Copper Strip (C11000) Description

High-Precision Copper Strip (C11000) is engineered from pure copper (Cu) using refined cold rolling and electropolishing techniques. It features tight tolerances and a smooth surface that minimises contact resistance. The controlled grain structure supports uniform electrical conductivity and efficient heat dissipation, providing practical benefits in complex circuitry and thermal management applications. Its consistent thickness is ideal for precision fabrication processes in industrial and electronic systems.

High-Precision Copper Strip (C11000) Applications

1.       Electronics
   - Used as a conductor in printed circuit assemblies to achieve efficient electrical transmission by leveraging its uniform thickness and smooth finish.
   - Applied as interconnects in semiconductor packaging to minimise resistance and ensure stable current flow through its inherent material purity.

2.       Industrial
   - Serves as a heat spreader in power modules to limit thermal gradients by utilising its high thermal conductivity and processed surface finish.
   - Employed in industrial bus bars to maintain consistent electrical performance by taking advantage of its dimensional precision and controlled oxide layer.

High-Precision Copper Strip (C11000) Packing

The copper strip is packaged in anti-scratch, moisture-resistant polyethylene bags and securely placed in rigid, cardboard containers. Each package includes clearly labelled batch and material information. It is recommended to store the strips in a cool, dry environment to minimise oxidation. Custom packaging options, such as additional cushioning or specialised containment, are available for specific handling requirements.

Frequently Asked Questions

Q1: What critical dimensional tolerances are maintained during manufacturing?
A1: The copper strip is processed with advanced cold rolling techniques, achieving dimensional tolerances within ±0.03 mm. Digital micrometry and optical inspection are integrated during production to verify these tolerances.

Q2: How is the surface quality controlled throughout production?
A2: Surface quality is managed using electropolishing followed by profilometry inspection. This ensures a smooth finish with minimal surface roughness, reducing contact resistance and supporting consistent conduction performance.

Q3: What storage conditions are recommended to maintain the strip’s properties?
A3: It is advised to store the copper strips in a cool, dry environment with relative humidity below 50%. Such conditions limit oxidation and maintain the strip’s controlled surface finish and dimensional integrity.

Additional Information

Copper metals have long been valued for their high electrical and thermal conductivity and are extensively utilised in applications requiring efficient power transmission and heat dissipation. Recent advances in cold working and surface treatment technologies have enhanced the material’s precision and finish, opening new possibilities in high-performance industrial applications.

Understanding the microstructural changes post-processing is crucial for predicting long-term performance. Material scientists continue to explore the effects of grain orientation and impurity control to further optimise copper’s characteristics for increasingly demanding operational conditions.
