What is Stainless Steel Foil?

Stainless Steel Foil is a cold-rolled, bright-annealed austenitic stainless steel (316L) with extreme thinness (0.01–0.05mm). Combining ultra-high strength, flexibility, corrosion resistance, and EMI shielding performance, it is engineered for 5G/6G precision electronics.

❓ Frequently Asked Questions

Q1: How does "Tearable Steel" differ from standard stainless foils?

A: It achieves extreme thinness (≤0.05mm) while maintaining 550MPa strength, hand-tearable flexibility, and burr-free blanking – critical for micro-electronics.

Q2: Why choose 316L over 304 for EMI shielding?

A: 316L's molybdenum content (2–3%) enhances corrosion resistance in humid/salty environments and stabilizes EMI performance.

Q3: How does Burr-Free Blanking reduce costs?

A: It eliminates grinding/plating steps, improving yield by 30%+ for micron-level parts such as RF connector shields.

Q4: Do you support small-batch customized orders?

A: Yes. We offer a "One-Roll MOQ" service for thickness, width, and surface customization.

Q5: What is the typical lead time for standard specifications?

A: Standard specifications are typically ready in stock and can be shipped within 3-15 days depending on the volume.

Q6: What surface treatments are available for the foil?

A: We provide several surface treatments including 2B (cold rolled), BA (bright annealed), and polished finishes to meet different industrial requirements.
