Good Conductivity and durability: copper foil film sheet offers good electrical conductivity, corrosion resistance, and processing performance. Waterproof and versatile: waterproof and moistureproof, capable of operating in various conditions; smooth surface supports reliable welding and brazing. Flexible and longlasting design: flexible enough to twist, bend, and tear; easy to use and designed for long service life. Material and finish: seamless brass with a polished finish; provides strength along with an attractive appearance. Use scenarios Electronics and electrical assemblies where conductivity and corrosion resistance are important in challenging environments. Crafting, jewelry making, or decorative applications that require a smooth, polished brass sheet that can be shaped. Welding or brazing projects in fabrication or that benefit from a seamless brass sheet with a polished finish.
