Finding flat metal stock that is already cut to size is one of the most time-consuming parts of any metalworking or jewelry project. Whether you are a hobbyist machinist, a jeweler needing ready-to-stamp blanks, or a maker building custom hardware, these brass and red copper solid round disc blanks eliminate the cutting step so you can focus on the craft. Each disc arrives with clean edges and a consistent thickness, ready for drilling, forming, engraving, or finishing.
These round disc blanks are available in two alloy types: Red Copper (T2 grade, 99.9% Cu) and Brass (H62 grade, approximately 62% Cu / 38% Zn). Thickness ranges from 0.3 mm to 6 mm (approximately 0.012 in to 0.236 in) and diameter ranges from 10 mm to 80 mm (approximately 0.39 in to 3.15 in). Each listing is sold in packs of 1, 2, or 4 pieces depending on the selected variant.
Typical use cases include copper disc blanks for jewelry stamping and pendant making, brass shim stock for precision mechanical fitting and gap adjustment, and decorative metal inlay work for woodworking and furniture restoration. Additional applications include DIY electrical grounding pads, custom gasket fabrication, and craft enameling base plates.
Choose Red Copper (T2, 99.9% Cu) for maximum electrical conductivity and corrosion resistance, or Brass (H62) for added strength and a warm golden tone — both available across the same size matrix.
Thickness from 0.3 mm to 6 mm and diameter from 10 mm to 80 mm give you the flexibility to match the exact blank size your project demands without custom cutting.
Each disc is pre-cut to a circular shape with consistent dimensions, saving setup time compared to cutting from sheet stock and reducing material waste.
Both T2 copper and H62 brass machine cleanly with standard tooling. They drill, mill, and stamp without cracking or excessive burring, making them ideal for precision DIY work.
Copper and brass naturally resist oxidation in typical indoor and moderate outdoor environments. T2 copper is especially suited for electrical and plumbing-adjacent applications where conductivity matters.
Order 1, 2, or 4 pieces per variant to match your project scale — whether you need a single prototype disc or a small batch for production runs.

Thinner discs (0.3 mm – 1 mm) are well-suited for jewelry blanks, shim stock, and decorative inlays where flexibility or low profile is needed. Mid-range thicknesses (1.2 mm – 2 mm) work well for structural brackets, custom gaskets, and enameling bases. Thicker discs (2.5 mm – 6 mm) are appropriate for machined parts, heavy-duty spacers, and applications requiring rigidity. Select your thickness from the Thickness x Diameter option above.
Red Copper (T2) is nearly pure copper (99.9% Cu), offering the highest electrical conductivity, excellent thermal conductivity, and strong corrosion resistance. It has a warm reddish tone and is softer, making it easier to cold-form and stamp. Brass (H62) is a copper-zinc alloy (~62% Cu, 38% Zn) that is harder and stronger than pure copper, with a golden appearance. Brass machines more cleanly at higher speeds and is preferred when structural strength or a decorative gold finish is required.
Both alloys offer good corrosion resistance in typical environments. Red Copper (T2) develops a natural patina over time when exposed to moisture and air, which acts as a protective layer. Brass (H62) is also corrosion-resistant but may tarnish in humid or saline environments. For prolonged outdoor exposure, applying a clear lacquer or protective coating is recommended to maintain appearance.
Yes. Both T2 copper and H62 brass are highly solderable and brazeable. T2 copper is compatible with standard electrical solder (tin-lead or lead-free) and silver brazing alloys. H62 brass solders well with soft solder and can be brazed with silver or brass brazing rods. Ensure surfaces are clean and flux is applied for best results.
For pendant and charm blanks, diameters of 10 mm – 25 mm (approx. 0.39 in – 0.98 in) are the most common. Larger discs (30 mm – 50 mm) work well for statement pendants, medallions, or decorative tags. If you plan to drill a hole for a jump ring, choose a diameter at least 4–5 mm larger than your intended finished size to allow for the hole and any edge finishing.
Red Copper (T2) discs are an excellent choice for electrical grounding pads due to their high conductivity. For shim stock applications requiring precise gap filling, select the thickness that matches your required clearance — thicknesses from 0.3 mm to 1 mm are most commonly used as shims. Brass (H62) is preferred for mechanical shim applications where higher hardness and wear resistance are needed.
The quantity per order depends on the variant you select. The Amount option shows 1 pcs, 2 pcs, or 4 pcs. Smaller diameter and thinner discs are typically available in larger pack quantities, while larger or thicker discs are sold in smaller quantities. The exact pack size for your chosen thickness and diameter combination is shown in the variant selector above.
