What is the measured surface resistance of the Atomfair AF-CUCR-6U50U coated copper foil, and how does it compare to the specified maximum?
The measured surface resistance is 10 milliohm, which is well below the specified maximum of ≤30 milliohm. This low resistance is beneficial for minimizing ohmic losses in conductive foil applications, particularly in battery current collectors.
What thickness and width range does this coated copper foil support, and what is the copper purity specification?
The foil is available in a thickness range of 6–50 μm and width up to 600 mm. The copper purity specification is ≥99.0%, with a measured purity of ≥99.5%. The coating achieves a cross-cut adhesion of 5B, ensuring strong bonding for demanding applications.
How does the surface dyne value of 40 dyn/cm (≥38 specification) affect wettability in electrolyte or coating processes?
The measured surface dyne value is 40 dyn/cm, exceeding the specification of ≥38 dyn/cm. This higher surface tension indicates improved wettability, which can enhance electrolyte wetting or coating adhesion in battery and conductive foil applications.
This salt-spray corrosion-resistant coated copper foil (model AF-CUCR-6U50U) delivers a measured surface resistance of 10 milliohm and a surface dyne value of 40, exceeding the ≤30 milliohm and ≥38 specifications respectively, with confirmed 5B cross-cut adhesion and corrosion resistance for laboratory current collector applications.
Positive
- Strong adhesion and low resistance: Cross-cut adhesion test achieves 5B, and surface resistance measures 10 milliohm against a ≤30 milliohm specification, ensuring robust bonding and high conductivity for foil-based current collectors.
- High surface tension and corrosion resistance: Surface dyne value of 40 surpasses the ≥38 specification, and alcohol rubbing and salt-spray corrosion resistance are confirmed, enhancing wettability and durability in corrosive environments.
Trade-offs
- Limited thickness and width range: Thickness is restricted to 6–50 μm and width ≤600 mm, which may not accommodate applications requiring thinner, thicker, or wider foil formats.
- Coating must be matched to foil geometry: The coating specification must be confirmed against the required foil width and thickness, requiring additional configuration effort and potentially longer lead times for custom variants.
