The chain is fine...but I ordered the wrong size. Nine links of the chain I ordered equals six of the size I wanted. My error...
How can I straighten out the springs? I can't use them coil uo as is.

When your project demands a flat brass stock that machines cleanly, solders reliably, and holds tight tolerances, finding the right thickness in the right size can be a real challenge. Whether you are a model engineer, jewellery maker, or workshop fabricator, this H62 brass sheet gives you a ready-to-use blank that skips the guesswork and gets straight to work.
Each piece is cut from H62 grade brass alloy — a copper-zinc composition known for its balance of strength, machinability, and warm golden appearance. Thickness options run from 4mm (approx. 5/32 in) through to 10mm (approx. 13/32 in), with widths and lengths ranging from 50mm × 100mm (approx. 2 in × 4 in) up to 500mm × 500mm (approx. 19.7 in × 19.7 in), covering a broad spectrum of project scales.
Typical applications include scale model chassis and structural components, hand-fabricated jewellery bezels and settings, engraving blanks for plaques and nameplates, electrical contact plates and busbar sections, and custom bracket or shim stock for mechanical assemblies. The flat-rolled surface finish makes it suitable for direct machining, filing, or chemical patination without additional preparation.

For jewellery bezels, settings, and decorative inlays, 4mm or 5mm is typically sufficient. For structural model components, brackets, or busbar sections that need to bear load or resist bending, 6mm to 10mm provides greater rigidity. If you are unsure, start with the thinnest option that meets your strength requirement — thinner stock is easier to cut and shape by hand.
H62 brass has a typical tensile strength of 330–420 MPa, which is adequate for light-to-medium mechanical applications such as shims, spacers, contact plates, and non-structural brackets. It is not recommended for high-load structural applications where steel or aluminium alloy would be more appropriate.
Brass does not rust (rust is specific to iron-based metals), but it will develop a natural patina over time when exposed to air and moisture. H62 brass has moderate corrosion resistance and performs well in dry indoor environments. For outdoor or high-humidity applications, a clear lacquer or wax coating is recommended to preserve the surface appearance.
Yes. H62 brass machines well with standard metalworking tools. A hacksaw, jigsaw with a metal-cutting blade, angle grinder, or bandsaw can all be used for straight cuts. For precision work, a milling machine or CNC router with appropriate feeds and speeds will produce clean edges. Always use cutting fluid or lubricant to extend tool life and improve cut quality.
Yes. H62 brass is widely used in jewellery fabrication for bezels, back plates, and structural components. The flat-rolled surface accepts engraving, stamping, and chemical patination (such as liver of sulphur or ferric chloride) well. Thinner variants (4mm–5mm) are most commonly chosen for jewellery work, while thicker pieces suit engraving plaques and nameplates.
Use the variant selector above to choose your preferred thickness (4mm, 5mm, 6mm, 8mm, or 10mm) and then select the width × length combination that best fits your project. If your required size falls between two listed options, select the next size up and trim to your final dimension. All pieces are supplied as individual flat blanks (1 piece per order).
Yes. H62 brass has excellent solderability and can be joined using standard soft solder with an appropriate flux (such as zinc chloride or rosin-based flux). It can also be brazed using silver brazing alloy for stronger joints. Ensure the surface is clean and free of oxide before soldering for best results.
