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 reliable conductivity and consistent thickness, standard sheet metal simply falls short. Whether you're a hobbyist building custom electronics, a maker fabricating heat spreaders, or a craftsperson working with decorative metalwork, you need a copper sheet that delivers exact dimensions and verified purity every time. This T2 copper flat plate sheet is engineered for makers, engineers, and DIYers who refuse to compromise on material quality.
Each sheet is cut from 99.9% pure T2 copper (CU), offering excellent electrical and thermal conductivity. Available in thicknesses from 0.1mm to 0.8mm (~0.004″ to ~0.031″), with a fixed sheet size of 300mm × 300mm (~11.8″ × 11.8″). The flat, smooth surface finish ensures consistent contact and clean cuts with standard metal shears or laser cutters.
Typical applications include DIY battery tab welding and spot-welding shims, custom RF shielding and EMI gaskets for electronics enclosures, heat spreader fabrication for LED arrays and power modules, and decorative copper inlay work for woodworking and jewelry projects.

For battery tab welding and spot-welding shims, 0.1mm–0.2mm is typically sufficient. For heat spreaders and thermal interface pads, 0.3mm–0.5mm offers a good balance of conductivity and rigidity. For structural shims, brackets, or decorative panels requiring more stiffness, 0.6mm–0.8mm is recommended. If you're unsure, start with 0.3mm as a versatile mid-range option.
T2 copper is a relatively soft, ductile metal — it is not intended for load-bearing structural applications. However, it provides excellent rigidity for thin shims, gaskets, and enclosure panels. For thicknesses of 0.6mm and above, the sheet holds its shape well under moderate mechanical stress. For high-load structural use, consider a harder copper alloy or brass instead.
Pure copper naturally oxidizes when exposed to air and moisture, developing a brownish or greenish patina (verdigris) over time. This patina is a natural protective layer and does not significantly affect electrical or thermal performance in most applications. For applications requiring a bright finish, apply a clear lacquer or store sheets in a sealed, dry environment when not in use.
Yes. T2 copper is highly solderable with standard rosin-core or lead-free solder and flux. It is also compatible with brazing using silver-based filler rods. For spot welding (e.g., battery tab applications), thinner gauges (0.1mm–0.2mm) work best. Note that copper's high thermal conductivity means you may need a higher-wattage soldering iron (60W+) to achieve proper heat transfer.
Yes, with the right setup. Fiber laser cutters handle copper well due to copper's high reflectivity to CO₂ lasers — a CO₂ laser is not recommended for cutting copper. CNC routers with carbide end mills can machine copper sheet effectively, especially at 0.3mm and above. The 300×300mm sheet size fits most desktop CNC and laser work envelopes. Always use appropriate feeds, speeds, and coolant to prevent work hardening.
T2 copper (also known as C11000 or ETP copper in international standards) is 99.9% pure copper with minimal impurities, making it one of the most electrically and thermally conductive copper grades available. It is softer and more workable than phosphor bronze or brass, and more conductive than copper alloys. T2 is the standard choice for electrical busbars, heat spreaders, and precision foil applications where conductivity is the primary requirement.
Each order includes 1 sheet of the selected thickness. The sheet dimensions are 300mm × 300mm. If you need multiple sheets or different thicknesses, simply add multiple items to your cart or contact us for bulk pricing inquiries.
