Core Material Features
Our 0.001mm ultra-thin high purity aluminum foil combines superior material properties with precision manufacturing technology, providing a stable and high-performance base material for your research and production work. Each performance index is strictly controlled in the production process to ensure stable and consistent product quality batch after batch.
Ultra-High 99.99%+ Purity
Refined to a minimum purity of 99.99% with strictly controlled total trace impurities, this aluminum foil maintains consistent chemical composition across every batch. The high-purity matrix ensures stable physical and chemical properties, eliminating performance variations caused by impurity elements and delivering dependable results for sensitive laboratory experiments and high-precision industrial processes.
0.001mm Ultra-Thin Gauge
Manufactured with state-of-the-art rolling technology to achieve an ultra-thin 0.001mm gauge. Each foil roll maintains uniform thickness distribution across the full width and length, making it perfectly suited for micro-scale applications, thin-film research, ultra-compact electronic components and precision lamination processes.
Excellent Thermal & Electrical Conductivity
The high-purity aluminum matrix preserves outstanding intrinsic thermal and electrical conductivity, providing efficient heat dissipation and stable current transmission. The material performs reliably as a thermal interface layer, conductive electrode substrate, electromagnetic shielding medium and heat dissipation component in both laboratory testing and industrial production environments.
Superior Chemical Inertness & Corrosion Resistance
The naturally formed dense oxide layer on the surface provides excellent corrosion resistance and chemical stability under most atmospheric, aqueous and mild chemical conditions. The material maintains structural integrity during long-term experimental cycles, is compatible with most common laboratory reagents, and resists oxidation and discoloration in routine storage and use.
Low Outgassing for Vacuum Environments
Produced with high-purity raw materials and clean manufacturing processes, the foil exhibits extremely low outgassing rates under high-vacuum conditions. It does not release volatile contaminants that could interfere with vacuum systems, sample surfaces or analytical instruments, making it ideal for vacuum evaporation, sputtering coating and high-vacuum experimental setups.
Excellent Formability & Workability
Supplied in fully annealed condition for maximum ductility and formability, the foil can be easily cut, bent, stamped, punched and formed into custom shapes without cracking or wrinkling. It adapts seamlessly to manual laboratory sample preparation as well as high-speed industrial stamping and slitting processes, supporting both small-batch R&D and volume production.
