Finding flat copper stock that's truly flat, consistently sized, and free of surface defects is a constant frustration for model makers, electronics hobbyists, and small-workshop fabricators. Whether you're building scale models, crafting custom bus bars, or prototyping circuit connections, dimensional inconsistency wastes time and materials. These 99.9% pure copper strip sheet metal plates are precision cut to give you a reliable, ready-to-use starting point every time.
Each plate is made from 99.9% electrolytic copper, delivering excellent electrical conductivity and a clean, smooth surface finish. Strips are available in widths from 10 mm to 12 mm (approx. 0.39"–0.47") and cross-section depths from 20 mm to 100 mm (approx. 0.79"–3.94"), all cut to a standard 200 mm (approx. 7.87") length. Thickness varies by size variant — see variant options for exact dimensions.
Typical applications include DIY copper bus bar fabrication for electrical panels, precision copper shim stock for model railway and RC vehicle builds, custom heat-spreader blanks for electronics cooling projects, and decorative metalwork for jewelry-making and craft projects requiring pure copper strip stock.

Select the width (10 mm or 12 mm) and depth (20 mm–100 mm) that match your required cross-section. For bus bar applications, calculate the current-carrying capacity based on cross-sectional area — a 10 mm × 20 mm strip (200 mm²) is suitable for lighter loads, while a 10 mm × 100 mm strip (1000 mm²) handles heavier currents. For model-making, choose a size that fits your scale and structural needs.
99.9% electrolytic copper is a relatively soft, ductile metal with a tensile strength of typically 200–250 MPa in the annealed condition. It is well-suited for forming, bending, and soldering in model-making, but is not intended for high-load structural applications. For decorative frames, bus bars, shims, and craft work, it performs reliably.
Copper naturally develops a patina (oxidation layer) when exposed to air and moisture over time. This patina is a thin oxide layer that actually slows further corrosion. For electrical applications, the contact surfaces should be kept clean. If you prefer a bright finish, a light polish or clear lacquer coating will maintain the appearance. The strips will not rust.
Yes. 99.9% copper is one of the most solderable metals available. It accepts standard rosin-core solder, silver solder, and brazing alloys without special flux in most cases. Clean the surface with isopropyl alcohol or fine abrasive before soldering for best results. The mill finish is compatible with most common soldering and brazing processes used in electronics and model-making.
Yes. These copper strips can be cut with tin snips, bench shears, or a hacksaw; filed and sanded with standard abrasives; drilled with HSS drill bits; and bent with a vise or sheet metal brake. No special tooling is required for typical hobbyist and light-fabrication work. Copper is softer than steel, so standard tools handle it easily.
The variants differ in cross-sectional dimensions (width × depth). A narrower, shallower strip (e.g., 10 mm × 20 mm) is lighter and suited for small-scale models, jewelry, or low-current electrical work. A wider, deeper strip (e.g., 12 mm × 50 mm or 10 mm × 100 mm) provides more material for larger bus bars, heavier structural elements, or projects requiring more copper mass. All variants share the same 200 mm length and 99.9% purity.
Absolutely. 99.9% copper is a popular choice for jewelry, decorative metalwork, and craft projects due to its warm color, workability, and ability to take a polished finish. It can be stamped, etched, formed, and patinated with common craft chemicals. The precision-cut edges reduce prep work compared to raw sheet stock.
