Product Story
When "Good Enough" Is the Smartest Choice
Not every application needs 99.99% ultra-high-purity copper foil. In shielding, heat dissipation and grounding, overall cost-effectiveness often matters more than extreme specifications. CIVEN standard-grade pure copper foil was built on this insight, delivering quality well above the industry average at a reasonable cost.
Copper content of ≥ 99.8% means the material retains excellent intrinsic electrical and thermal conductivity. Conductivity ≥ 98% IACS and thermal conductivity close to the theoretical value of pure copper reflect CIVEN's consistent commitment to raw material quality: we never use recycled scrap copper, and every batch is made from cathode copper meeting GB/T standards, sourced from certified smelters.
From ultra-thin 12 microns to thicker 90 microns, with widths covering the full range from 4 mm to 640 mm, this flexibility lets one material serve both precision electronic components and large-area shielding cans. For customers who need multiple specifications, this means simpler supply chain management.
A smooth surface free of pinholes and oxidation spots may sound like a basic requirement, yet it is often a pain point in real-world purchasing. CIVEN pure copper foil undergoes 100% surface inspection before shipment and is vacuum-packed so it arrives as bright as new. Because we know that the surface condition of the material directly affects customers' first impression and downstream processing efficiency.
