The global demand for stainless steel foil has surged significantly, driven by the rapid miniaturization of electronic devices and the rise of green energy. As a critical material with a thickness typically ranging from 0.01mm to 0.1mm, it serves as the backbone for high-tech manufacturing in Asia, Europe, and North America.
With the advent of Industry 4.0, precision cold-rolled stainless steel foil is no longer a commodity but a strategic asset. From aerospace sensors to 5G base station components, the material's mechanical properties—such as high tensile strength and extreme corrosion resistance—make it irreplaceable.
Manufacturers are shifting focus toward high-performance alloys like 316L, 301EH, and 347. These grades provide superior thermal stability and EMI shielding capabilities, which are essential for the latest generation of mobile communication and automotive electronics.
The Stainless Steel Foil market is evolving toward "Thinner, Stronger, and More Specialized" products. As a leading manufacturer, Dongguan TEDDI STEEL Co., Ltd. is at the forefront of these developments.
Our 0.01mm to 0.08mm high-precision foils are optimized for high-speed stamping. These are vital for manufacturing connectors, shrapnel, and micro-motor components where dimensional accuracy is non-negotiable.
Specifically designed 304/316SS Lithium-Ion Battery Foils provide the necessary chemical stability for current collectors and battery casings, supporting the global shift toward electric vehicles (EVs).
With grades like AISI 347 and SUS316L, we supply materials for bellows, gaskets, and medical surgical instruments that require biocompatibility and resistance to extreme temperatures.

Located in Dongguan, the heart of global manufacturing, TEDDI STEEL leverages a mature ecosystem. This allows us to offer competitive pricing without compromising on the precision required for ultra-thin foils.
Our facilities utilize the latest cold-rolling technologies capable of producing foils with a thickness tolerance of ±0.001mm. This expertise is critical for high-end applications like 5G EMI shielding and precision circuit etching.
We understand the urgency of global industrial projects. Our logistics network ensures that whether you need 301 mirror-finished strips or 430 grade foils, delivery is streamlined and documented with full MTC (Material Test Certificate) compliance.
Industrial buyers across the globe—from Germany's automotive giants to Silicon Valley's tech innovators—share common requirements for stainless steel foil procurement. At TEDDI STEEL, we address these through a rigorous E-E-A-T compliant approach:
1. Material Integrity: We use only premium VOD/AOD refined billets. This ensures that our 316L foils have the low carbon content necessary for superior welding and corrosion resistance in marine and chemical environments.
2. Surface Perfection: For mirror-finished (BA) and 2B finishes, we employ specialized tension leveling and bright annealing to ensure the surface is free of scratches, pits, or oil stains—critical for high-end decorative and functional electronic parts.
3. Customization Depth: Unlike standard suppliers, we offer "Short Delivery" on non-standard widths. Whether you require a 3.0mm narrow strip or a 300mm wide foil, our slitting lines are calibrated for maximum precision and minimal edge burr.
4. Technical Documentation: Reliability is built on transparency. Every shipment is accompanied by detailed chemical analysis and mechanical property reports, meeting ASTM, AISI, SUS, and EN standards.
