Product Selection Differences for Expanded Oxygen Free Copper (OFC) Sheet

When selecting Expanded Oxygen Free Copper (OFC) Sheet, there are several key differences to consider:

1. Purity and Oxygen Content: Oxygen Free Copper is known for its high conductivity and low oxygen content, which minimizes the risk of oxidation and ensures better electrical performance. When selecting OFC sheets, check the purity level as higher purity OFC will have better electrical and thermal conductivity.

2. Grain Structure: Consider the grain structure of the OFC sheet as it can impact its mechanical and electrical properties. Fine-grained OFC sheets are usually preferred for applications requiring high conductivity and strength.

3. Thickness and Dimensions: Choose the OFC sheet with the appropriate thickness and dimensions based on your specific application requirements. Ensure that the sheet can be easily processed and formed without compromising its properties.

4. Surface Finish: The surface finish of the OFC sheet is crucial for applications where contact resistance and surface smoothness are important. Opt for sheets with a smooth and clean surface finish to ensure optimal performance.

5. Manufacturer Reputation: Consider the reputation and track record of the manufacturer when selecting OFC sheets. Established manufacturers with a history of producing high-quality OFC products are more likely to provide reliable and consistent performance.

6. Certifications and Standards: Check if the OFC sheet meets industry specifications and standards for conductivity, purity, and reliability. Certifications such as ASTM and RoHS compliance can ensure the quality and performance of the OFC sheet.

By considering these factors, you can select the most suitable Expanded Oxygen Free Copper (OFC) Sheet for your specific application requirements.
