When a project demands a flat, burr-free metal blank that cuts cleanly and solders reliably, finding the right disc in the right size can be a real bottleneck. Whether you're a hobbyist jeweller, a model engineer, or a workshop fabricator, H62 brass discs give you a ready-to-use round blank without the waste and time of cutting your own circles from sheet stock.
These solid H62 brass discs are machined from copper-zinc alloy 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 consistent circular profile suited to further machining, stamping, or finishing.
Typical applications include decorative inlay discs for woodworking and furniture making, electrical contact blanks and shim stock for light engineering, jewellery and craft base blanks for etching or enamelling, and gasket or spacer prototypes in plumbing and HVAC repair work.

Measure the circular recess, hole, or area your disc needs to fit or cover, then select the next size up if you need to trim to fit, or the exact size if you want a ready-to-use blank. The diameter options run from 10mm to 300mm in increments, so you can match common metric sizes directly. If you are making a gasket or shim, match the outer diameter to the flange or bore you are sealing.
For jewellery blanks, decorative inlays, and light craft work, 1mm is typically sufficient and easiest to cut or pierce. 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.
H62 brass has moderate corrosion resistance and performs well in dry indoor environments and mild atmospheric conditions. In outdoor or humid environments, the surface will develop a natural patina over time. For long-term outdoor exposure, consider applying a clear lacquer or wax coating to slow oxidation. H62 is not recommended for marine or highly corrosive chemical environments without additional surface protection.
Yes. H62 brass solders readily with standard soft solders (tin-lead or lead-free) using an appropriate flux such as a zinc chloride or rosin-based 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 overheating, as prolonged high heat can cause zinc volatilisation and weaken the joint.
Yes. H62 brass machines well with standard HSS or carbide tooling. 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, angle grinder, or lathe parting tool. Always use appropriate cutting fluid or lubricant when machining.
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. H62 brass discs are a popular choice for jewellery blanks, pendant bases, and stamping stock. The 1mm thickness is well suited to hand stamping with letter or design punches, and the golden colour of brass provides an attractive base for patination, enamelling, or plating. For heavier stamping or forming operations, the 1.5mm thickness is recommended to prevent cracking or distortion.
