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, dimensionally accurate metal blank that machines cleanly and resists corrosion without special coatings, finding the right stock in the right size is half the battle. Whether you are a hobbyist building custom brackets, a maker crafting decorative inlays, or a technician shimming mechanical assemblies, these H62 brass sheet squares give you a ready-to-use starting point without the waste of cutting down oversized stock.
Each piece is cut from H62 copper-zinc alloy flat bar stock. The range spans thicknesses from 0.1 mm (approximately 0.004 in) up to 10 mm (approximately 0.394 in), and face dimensions from 10×10 mm (approx. 0.39×0.39 in) up to 200×200 mm (approx. 7.87×7.87 in). Pieces are supplied in quantities of 1, 2, or 4 per order depending on the selected variant.
Typical applications include DIY shim stock for levelling machinery and furniture, engraving blanks for personalised nameplates and jewellery, electrical contact spacers in low-voltage circuits, decorative inlay panels for woodworking and leathercraft, and prototype flat brackets for maker and engineering projects.

For shim stock and precision gap-filling, thicknesses of 0.1–0.5 mm are typical. For engraving blanks and decorative plates, 0.5–2 mm provides a good balance of rigidity and ease of cutting. For structural brackets or load-bearing spacers, 2–10 mm is recommended. If you are unsure, start with a mid-range thickness such as 1–1.5 mm and adjust based on your test fit.
H62 brass offers moderate tensile strength suitable for light-to-medium mechanical applications such as spacers, shims, and non-structural brackets. It is not intended for high-stress structural components or applications subject to heavy impact loads. For those uses, consider steel or aluminium alloys instead.
H62 brass does not rust (it contains no iron), but it can develop a natural patina or tarnish over time when exposed to air and moisture. For indoor decorative applications this patina is often desirable. For applications requiring a bright finish, apply a clear lacquer or metal polish after installation. Avoid prolonged exposure to ammonia-based cleaners, which can cause stress corrosion cracking in brass.
Yes. H62 brass is one of the more machinable copper alloys. Thin sheets (0.1–0.5 mm) can be cut with sharp scissors, a craft knife, or tin snips. Thicker pieces (0.5 mm and above) are best cut with a hacksaw, jigsaw with a metal blade, or CNC router. Drilling is straightforward with standard HSS drill bits. Laser engravers can mark the surface effectively on thinner sheets.
Yes. H62 brass accepts soft solder (tin-lead or lead-free) with a mild flux, and silver brazing alloys with an appropriate flux. Clean the surface with fine abrasive paper or a degreaser before soldering to ensure a strong joint. Avoid overheating, as prolonged high heat can cause zinc fuming and weaken the joint.
Choose 1 Pcs if you need a single piece for a one-off project or want to test a size before ordering more. Choose 2 Pcs if your project requires a matched pair (e.g., two identical shims or two decorative panels). Choose 4 Pcs if you are working on a batch project, need spares for practice cuts, or want to stock a commonly used size. Note that not all size-quantity combinations are available — check the variant selector for your specific combination.
Order the smallest square that fully contains your finished shape to minimise waste. For example, if your finished part is 35×60 mm, order the 50×100 mm variant and cut to shape. Always add a few millimetres of margin for clamping and finishing allowance.
