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 electrical conductivity, thermal performance, and long-lasting corrosion resistance, standard sheet metal simply falls short. Whether you're a hobbyist fabricating custom bus bars, an electrician sourcing grounding strips, or a craftsperson cutting decorative inlays, this T2 pure copper plate sheet gives you the exact thickness and dimensions you need without compromise.
Each sheet is made from T2-grade pure copper (≥99.9% Cu), laser-cut to clean, burr-minimized edges. Available in widths and lengths ranging from 100mm × 100mm to 200mm × 200mm (approximately 3.94" × 3.94" to 7.87" × 7.87"), with thickness options spanning 0.8mm to 5.0mm (0.031" to 0.197"). Sold individually (1 Pcs) or in pairs (2 Pcs) to suit your quantity needs.
Typical use cases include DIY electrical grounding plates and bus bar fabrication, heat-sink shims and thermal interface layers in electronics repair, and decorative metalwork such as etching blanks, jewelry bases, and architectural inlay panels — all applications where a pure copper sheet with consistent thickness is essential.
T2 copper delivers outstanding electrical conductivity (typically ~58 MS/m) and thermal conductivity (~390 W/m·K), making it the go-to choice for electrical and heat-management applications.
Each sheet is laser-cut for clean, consistent edges with minimal burring, reducing finishing time and ensuring accurate fit in precision assemblies.
Choose from seven thickness options — 0.8, 1.0, 1.5, 2.0, 3.0, 4.0, and 5.0mm — to match your structural or conductivity requirements exactly.
Select from 100×100mm, 100×150mm, or 200×200mm formats. All dimensions are cut to nominal size with standard metalworking tolerances.
Copper's inherent oxidation behavior forms a stable patina over time that protects the base metal, making these sheets suitable for both indoor and sheltered outdoor applications.
T2 copper is soft enough to cut, bend, drill, and solder with standard tools, yet rigid enough to hold shape in structural shim and busbar applications across the full thickness range.

For electrical grounding strips and light bus bars, 0.8mm–1.5mm is typically sufficient. For structural shims, heat spreaders, or heavier current-carrying applications, 2.0mm–5.0mm provides greater rigidity and cross-sectional area. If you're unsure, select a thicker option — it's easier to thin copper than to add material.
T2 is the Chinese national standard designation for electrolytic tough-pitch (ETP) copper, closely equivalent to ASTM C11000 (C110). Both specify ≥99.9% copper content and share nearly identical electrical and thermal properties, making T2 sheets a direct functional equivalent for most ETP copper applications.
Copper naturally oxidizes when exposed to air and moisture, forming a brownish or greenish patina (verdigris). This patina is a stable oxide layer that actually protects the underlying copper from further corrosion. For applications requiring a bright finish, apply a clear lacquer or store sheets in a sealed bag until use.
Yes. T2 pure copper solders and brazes readily with standard rosin-core or acid-core solder and common silver or phosphor-copper brazing alloys. Clean the surface with fine abrasive or flux before joining to remove any oxide layer for a strong bond.
Yes for CNC routing and milling — use carbide tooling and appropriate feeds/speeds for copper. For laser engraving, note that bare copper is highly reflective to CO₂ lasers; fiber lasers or CO₂ lasers with a marking compound (e.g., Cermark) are recommended for clean engraving results.
Selecting "1 Pcs" gives you a single sheet of your chosen size and thickness. Selecting "2 Pcs" gives you two identical sheets at a bundled price, which is more economical if you need matched pairs for symmetric assemblies, prototyping extras, or backup material.
Copper performs well in sheltered outdoor environments. In direct exposure to rain and humidity, it will develop a patina over time. For fully exposed outdoor use, consider applying a clear protective coating if a bright appearance is required. The base metal will not rust or structurally degrade under normal outdoor conditions.
