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 reliable, machinable flat metal stock and you can't justify buying a full sheet, these H62 brass sheet plate guillotine offcuts are exactly what you need. Designed for hobbyists, model engineers, jewellers, and small-workshop fabricators who want precise, ready-to-use pieces without the waste of oversized stock.
Each piece is cut from H62 brass alloy — a copper-zinc alloy known for its good machinability, moderate strength, and warm golden appearance. Thickness options range from 0.3 mm (approx. 0.012 in) up to 8 mm (approx. 0.315 in), with flat dimensions spanning from 50 mm × 50 mm (approx. 2 in × 2 in) up to 300 mm × 300 mm (approx. 11.8 in × 11.8 in). Quantity options of 1, 2, or 4 pieces per order let you buy exactly what you need.
Typical applications include DIY electrical contact shims and spacers, decorative inlay work for woodworking and knife-making, small enclosure panels and brackets for electronics projects, and precision shimming in mechanical assemblies where a non-ferrous, corrosion-resistant flat stock is required.

Thinner gauges (0.3 mm – 1 mm) are ideal for shims, gaskets, decorative inlays, and flexible bending applications. Mid-range thicknesses (1.2 mm – 3 mm) suit brackets, small panels, and structural tabs. Thicker stock (4 mm – 8 mm) is suited to machined blocks, heavy-duty spacers, and parts requiring tapping or threading. If you are unsure, select the variant closest to your required finished dimension, allowing for any machining stock removal.
H62 brass has a tensile strength typically in the range of 330–470 MPa depending on temper, which is adequate for most light structural, decorative, and functional applications. It is softer than steel but significantly easier to machine, solder, and finish. For applications requiring higher strength, consider thicker variants or consult a materials engineer.
Brass naturally develops a patina (surface oxidation) over time when exposed to air and moisture, shifting from bright gold to a darker amber or brown tone. This is a normal characteristic of the alloy and does not affect structural integrity. To maintain a bright finish, apply a clear lacquer or metal polish after cleaning. For outdoor or high-humidity environments, periodic maintenance is recommended.
Yes. H62 brass solders readily with standard soft solders (tin-lead or lead-free) using an appropriate flux. It can also be silver-brazed for higher-strength joints. Ensure the surface is clean and free of oxidation before soldering. Avoid overheating thin gauges (under 0.5 mm) as they can warp or develop pinholes.
Drilling is straightforward on all thicknesses using standard HSS drill bits — use a slow feed rate and cutting fluid for clean holes. Tapping is practical on thicknesses of 2 mm and above, depending on the thread size required. For very thin sheets (under 1 mm), consider using rivets, adhesive, or through-bolts with a backing plate instead of tapped threads.
The quantity option lets you match your exact project needs. Order 1 piece for a single prototype or repair. Choose 2 pieces if you need a matched pair (e.g., symmetrical brackets or test and production parts). Select 4 pieces for small batch projects, to have spares for practice cuts, or when working on repetitive assemblies. Pricing per piece generally decreases with higher quantities in the same size.
The two flat dimensions refer to the length and width of the sheet piece. For example, 50×100 mm gives you a rectangular piece approximately 2 in × 4 in, while 100×100 mm gives a square piece approximately 4 in × 4 in. Choose the shape that best fits your layout to minimise waste. All pieces are guillotine-cut with straight edges on all four sides.
