A2/304 Stainless Steel Foil Sheet 0.01mm-1mm Thick Fine Plate Metal Strip Roll

For gaskets and shims, 0.01 mm–0.1 mm is typical. EMI shielding wraps generally use 0.05 mm–0.2 mm. Structural brackets or heat shields that need rigidity usually start at 0.3 mm and above. If you are unsure, order a 1 m sample of two thicknesses and test before committing to a longer roll.

Yes — "18/8" is a common shorthand referring to the approximate 18% chromium and 8% nickel composition of AISI 304 (A2 grade). The two designations describe the same alloy family. A2 is the ISO designation used in fastener and sheet standards, while 304 is the AISI/SAE designation more common in North American engineering specs.

A2/304 stainless steel resists rust in most outdoor and humid environments due to its passive chromium-oxide surface layer. However, it is not fully immune: prolonged exposure to chloride-rich environments (coastal salt air, de-icing salts) can cause pitting over time. For marine or high-chloride applications, A4/316 grade is a better choice.

Thicknesses up to 0.3 mm can typically be cut cleanly with sharp tin snips, rotary cutters, or a craft knife and steel rule. For 0.4 mm–1 mm, aviation snips or a bench-mounted guillotine shear produce cleaner edges. Laser cutters rated for stainless steel work well across all thicknesses. Always deburr cut edges before handling.

Yes. The 2B-style mill finish provides a consistent, low-roughness surface that bonds well with structural epoxies, cyanoacrylates, and pressure-sensitive adhesives after light abrasion or solvent degreasing. For best adhesion, wipe the surface with isopropyl alcohol immediately before bonding to remove any residual oils from handling.

Measure the widest single piece you need to cut from the strip. Choose the next standard width up — 50 mm, 100 mm, 200 mm, or 300 mm — to avoid splicing. If your pieces are narrower than 50 mm, the 50 mm roll is the most economical starting point. For large flat panels, the 300 mm width reduces the number of seams needed.

Stainless steel foil provides moderate EMI/RFI attenuation, particularly effective at higher frequencies. Thicknesses of 0.05 mm–0.2 mm are commonly used to line enclosures, wrap cables, or create Faraday-style barriers in electronics projects. For demanding RF shielding applications requiring very high attenuation, copper or mu-metal foil may be more appropriate.
