Sourcing a flat, consistently sized copper blank without cutting your own circles from sheet stock is a common frustration for electricians, jewellers, and workshop fabricators alike. T2 copper discs give you a ready-to-use round blank with the conductivity and workability that only pure copper can deliver — no alloy compromises, no scrap waste from hand-cutting.
These solid T2 copper discs are formed from 99.9%+ pure copper sheet and are available in three thicknesses — 1mm (~0.039 in), 1.2mm (~0.047 in), and 1.5mm (~0.059 in) — with diameters spanning 10mm (~0.39 in) to 300mm (~11.81 in). Each disc features flat, parallel faces and a clean circular profile ready for further machining, forming, or finishing.
Typical applications include electrical contact blanks and bus bar components for light engineering, jewellery and craft base blanks for enamelling, patination, or repoussé work, decorative inlay discs for woodworking and furniture making, and gasket or shim prototypes for plumbing and HVAC repair.

Measure the circular recess, hole, or area your disc needs to fit or cover, then select the matching size or the next size up if you need to trim to fit. Diameter options run from 10mm to 300mm in metric increments, making it straightforward to match common metric component sizes. For gaskets or shims, match the outer diameter to the flange or bore you are sealing.
For jewellery blanks, enamelling bases, and light craft work, 1mm is typically sufficient and the easiest to pierce, cut, or form by hand. For shims, spacers, and components that need to hold their shape under moderate load, 1.2mm offers a useful step up in rigidity. For stamping, forming, or applications where the disc will be machined further, 1.5mm provides the most material to work with and the greatest structural stiffness.
Yes. T2 copper's near-pure composition (≥99.9% Cu) gives it electrical conductivity typically at or above 97% IACS, making it one of the most conductive commercially available copper grades. These discs are suitable for electrical contact blanks, grounding pads, bus bar components, and heat-spreader applications. For comparison, brass and bronze alloys have significantly lower conductivity and are not suitable substitutes where electrical performance is critical.
Yes. T2 copper solders readily with standard soft solders (tin-lead or lead-free) using an appropriate flux such as a rosin or zinc chloride flux. It can also be brazed using silver brazing alloys at higher temperatures. Clean the surface with fine abrasive paper or a degreaser before joining to ensure a sound bond. Avoid prolonged overheating, as excessive heat can cause surface oxidation that interferes with wetting.
Yes. T2 copper machines well with standard HSS or carbide tooling, though it is softer and more ductile than brass, so sharp tools and appropriate cutting speeds are recommended to avoid built-up edge. It can be drilled, turned on a lathe, filed, sanded, and polished using conventional workshop equipment. For cutting smaller discs to shape, tin snips or a jeweller's saw work well on the 1mm thickness; thicker discs may require a hacksaw or lathe parting tool.
Pack quantity varies by diameter. Smaller diameters (10mm to 50mm) are available in packs of 2 or 4 pieces depending on the variant selected. Larger diameters (55mm to 300mm) are sold as individual pieces (1 PCS). Select your preferred Diameter, Thickness, and Packing QTY combination from the variant dropdowns above before adding to cart.
Yes. T2 copper discs are a popular choice for jewellery blanks, pendant bases, and craft metalwork. The pure copper composition is ideal for vitreous enamelling, as it bonds well with enamel powders and produces vivid colour results. For repoussé and chasing work, the 1mm thickness is easiest to work by hand; for heavier stamping or forming, the 1.5mm thickness is recommended to prevent cracking or tearing.
