H62 Brass Round Disc Blanks — Precision-Cut Solid Plates for DIY & Engineering
Whether you're a maker, jeweler, engineer, or hobbyist, sourcing flat brass blanks that are truly flat, consistently sized, and free of burrs is a constant challenge. These H62 brass disc blanks are precision-cut from solid brass sheet stock, giving you a clean, ready-to-use starting point for stamping, engraving, turning, or fabrication work.
Each disc is cut from H62 grade brass — a copper-zinc alloy (approximately 62% copper, 38% zinc) known for its excellent machinability, moderate strength, and attractive golden finish. Available in diameters from 50mm to 300mm (approximately 2" to 11.8") and thicknesses from 0.3mm to 5mm (approximately 0.012" to 0.197"), with 1 Pcs or 2 Pcs quantity options per order.
Common applications include clock faces and gear blanks, jewelry and pendant bases, electrical contact plates, decorative inlays and hardware accents, and prototyping or machining stock for small workshops.

❓ Frequently Asked Questions
What is H62 brass and how does it differ from other brass grades?
H62 is a standard Chinese brass grade containing approximately 62% copper and 38% zinc. It offers a good balance of strength, machinability, and corrosion resistance. Compared to H65 or H68 (higher copper content), H62 is slightly harder and more economical, making it well-suited for general fabrication, stamping, and machining applications.
How do I choose the right diameter and thickness for my project?
Select a diameter at least 5–10mm larger than your finished part to allow for edge cleanup and machining. For thickness, consider the structural load: 0.3–0.5mm is suitable for decorative or lightweight applications; 1–2mm for general fabrication; 3–5mm for structural or heavy-duty machining. Use the variant selector above to find your exact size combination.
Are the edges smooth and ready to use, or do they need finishing?
The discs are cut with clean edges and are generally ready for most applications. However, for precision work or where sharp edges are a concern, a light pass with a file or deburring tool is recommended. Thicker discs (3mm+) may have slightly more pronounced cut edges.
Can these brass discs be soldered or welded?
Yes. H62 brass solders well with standard silver solder or soft solder (tin-lead or lead-free). Brazing is also possible. Fusion welding is less common for thin brass sheet but can be done with appropriate filler and shielding gas. Always clean the surface before joining.
Will the brass discs tarnish or corrode over time?
H62 brass will naturally develop a patina (darkening or slight oxidation) when exposed to air and moisture over time. This is normal and can be polished away or left as a decorative finish. For long-term corrosion protection, consider applying a clear lacquer or wax coating after fabrication.
What is the difference between ordering 1 Pcs vs 2 Pcs?
The "Amount" option lets you choose how many discs of the selected size you receive per order. Selecting "2 Pcs" gives you two identical discs at a discounted per-unit rate compared to ordering two separate "1 Pcs" quantities. This is ideal when you need matched pairs or want a spare.
Can I use these discs for jewelry making or metal stamping?
Yes. Thinner discs (0.3mm–1mm) are popular for pendant blanks, coin-style jewelry, and metal stamping projects. The smooth surface accepts stamps, engraving, and patina treatments well. Larger diameters are suitable for decorative plates, clock faces, or wall art bases.
