Stainless Steel Foil (Ultra-Thin 304 / 316L / 430, 0.02-0.10 mm, Slit Edge, Bright Annealed)

Standard production range is 0.02 to 0.10 mm. For development or pilot projects we can produce down to 0.01 mm on request, with longer lead time and higher per-kg price. Below 0.02 mm the foil is typically considered 'ultra-thin strip' rather than 'foil'.

316L is preferred for medical and implant-related applications due to its lower nickel sensitivity, higher pitting resistance in body fluids, and better biocompatibility after electropolishing and passivation. 304 is acceptable for non-implant medical devices such as surgical instrument wraps and diagnostic test strips.

Yes. Foil can be supplied as pancake coils (single-layer wound, easier to unwind in automated lines) or as level-wound spools on plastic or steel cores. Pancake OD is typically 200-400 mm; spool lengths up to 5000 m depending on dimensions.

Standard MOQ is 50 kg per specification (grade, thickness, width, finish). Stock items ship within 7-10 days; custom thickness, width or grade requires 25-35 days. Sample coils (5-10 kg) are available on request for qualification.
