Moistureproof design for reliable performance in any environment. The copper sheet maintains a smooth surface and is well suited for welding and brazing. conductivity. Made from 99.9% copper, it delivers strong heat transfer and electrical conductivity. Its performance remains stable across typical temperature and pressure changes. Surface protection. A doublesided protective film is attached to prevent scratches during handling, cutting, and processing. Material and durability. purity copper provides dependable electrical and thermal properties with a smooth finish for easy fabrication. Size and compatibility. Available in standard sheet sizes to fit a range of projects and fabrication workflows. Practical applications. Electronics and electrical assemblies for heat dissipation, shielding, or grounding needs. Welding and brazing projects as a compatible base or contact sheet. DIY crafts, model making, prototyping, and other copper sheet applications that require a smooth, protected surface. How it solves common problems. Moistureproof design reduces corrosion risk in humid or damp environments. purity copper minimizes energy loss and supports efficient thermal management. Protective film reduces surface damage during transport and setup, keeping the working surface pristine.
