Material that Balances Copper's Heat Dissipation, Conductivity, and Paper's Processability "Copper Fiber Sheet"
A sheet made entirely of copper fibers, produced with advanced papermaking technology
This lightweight and flexible sheet, made entirely of copper fibers, combines copper’s excellent electrical and thermal conductivity with the porosity and flexibility of paper. We offer functional sheets for high-current electronic devices that enable thinner profiles, lighter weight, and greater design flexibility. [Features] 1. Effective thermal management through excellent heat dissipation - High specific surface area due to porous structure (10 times bulk ratio at same thickness) - Excellent air permeability - Thermal conductivity of copper material (20 times higher than stainless steel) 2.High electrical conductivity same level as copper bulk - High electrical conductivity (50 times higher than Stainless Fiber Sheet) (370 times higher than carbon fiber) 3. Flexibility like paper - Absorbs thermal dimensional changes at joints with dissimilar materials, enabled by its porous structure - Capable of folding, bending, and conforming to uneven surfaces - Suitable for use in movable and vibrating components 4. Space-saving and lightweight design - Controlled porous structure (adjustable porosity) - Uniform porous structure at thicknesses below 100 μm - Approximately one-third the weight of bulk (foil) for the same volume 5. Shape processing and rust/oxidation prevention treatment - Easy workability with scissors - Shape processing such as bending and forming - Various coating surface treatment
