xThin Brass Foil Built for Precision Work
RapidKeen brass foil is a thin, flat-rolled copper-zinc material supplied below 0.15 mm, in both rolled coils (brass foil roll / brass foil coil) and cut-to-length flat sheets. Sometimes called brass shim stock or thin brass sheet, it combines steady electrical conductivity, natural corrosion resistance and a bright gold-like finish, and it punches, etches, forms and solders cleanly for electronics, hardware and decorative work.
How Brass Foil Is Supplied
Rolls & Coils
Brass foil roll / brass coil form for continuous stamping, slitting and automated feeding, slit to the width you need.
Cut-to-Length Sheets
Flat brass foil pieces cut from coil for hand work, lay-up, shim packs and small-batch fabrication.
Micron Thickness
Every foil gauge is quoted in microns / mm below 0.15 mm, so very thin, uniform stock is easy to specify.
Material, Alloy & Temper
Our standard brass foil is produced from alloy 260 (C26000), widely known as cartridge brass or yellow brass — the most common and economical 70/30 brass for thin-gauge work. Additional yellow brass alloys such as 268 / 272 can be arranged. Choose the temper that matches your forming job:
- Soft / annealed (O): deepest forming, bending and wrapping.
- Half-hard (H02): balanced stiffness and formability, the everyday default.
- Hard: spring-like contact parts, clips and flat shims that must hold shape.
Natural mill finish; PVC protection or a brushed / polished surface can be added on request. Manufactured to the ASTM B36 brass product standard.
Where Brass Foil Is Used
Because thin brass foil is easy to punch, etch, bend and solder, it works equally well in functional electronic parts — shielding, contacts, flexible connectors and precision brass shim stock — and in visible pieces such as nameplates, lamp trim, furniture inlay and craft projects that need a real brass look.

Custom Slitting & Cutting
Send the thickness, width and length (or coil weight) your project needs and brass foil is slit to width or cut to length accordingly. Standard gauges ship from stock, while custom widths, tempers or finishes are produced to order based on fabrication complexity.
Shipping & Delivery Time
Processing: in-stock standard brass foil orders are dispatched within 1–5 business days. Custom-cut or made-to-order foil needs extra processing time that increases with fabrication difficulty.
Transit: after the order ships, delivery normally takes 7–15 days.
Custom Order Returns
Custom brass foil is cut or processed to your exact dimensions. Once cutting or fabrication has started, a custom order cannot be cancelled, returned or exchanged. Please confirm thickness, alloy, temper, width and length before ordering.
Brass Foil Questions
Is brass foil the same as brass shim stock?
“Brass shim stock” is the common workshop name for very thin brass foil used as spacers and wear shims — the same material, named for its shimming use. Both are available as rolls or flat sheets.
Brass foil vs thin brass sheet — what is the difference?
The difference is thickness and form. Brass foil is the thinnest flat-rolled grade (under 0.15 mm) and is often coiled; thicker, wider flat material is sold as brass sheet. Narrow coiled material in between is ordered as brass strip.
Which temper should I choose?
Use soft annealed foil for deep forming and wrapping, half-hard (H02) for general stamping, and hard foil for spring contacts and flat shims that must stay rigid.
Can the foil be supplied in a custom width?
Yes — brass foil rolls are slit to your requested width, and flat sheets can be cut to your length for shim packs, blanks and production runs.
