T2 Copper Flat Bar & Sheet Plate — Solid Copper Stock for Precision DIY & Electrical Work When your project demands a material that conducts electricity reliably, resists corrosion over time, and machines cleanly without cracking, generic metal bar stock simply falls short. Whether you are a hobbyist building custom bus bars, a maker fabricating heat sinks, or a small workshop cutting shims and spacers to exact tolerances, the T2 copper flat bar delivers the dimensional accuracy and material consistency your work requires. Each piece is made from T2-grade solid copper — a commercially pure copper alloy with a copper content of typically 99.9%, offering excellent electrical and thermal conductivity. Available in thickness options from 3mm to 15mm (approximately 0.12 in to 0.59 in) and widths from 8mm to 100mm (approximately 0.31 in to 3.94 in), with lengths of 100mm (approx. 3.94 in) or 500mm (approx. 19.69 in). The flat bar profile features a smooth, mill-finished surface with square edges and consistent cross-section throughout. Typical applications include copper bus bar fabrication for electrical panels, custom grounding straps and bonding conductors, heat spreader plates in DIY electronics cooling builds, decorative inlay strips for woodworking and furniture making, and precision shim stock for mechanical assemblies requiring tight tolerances. ⚡ Compatibility Note: Suitable for electrical, thermal, and structural applications. T2 copper is compatible with standard copper soldering, brazing, and mechanical fastening. Not recommended for direct contact with ammonia-based environments without protective coating. ✅ Key Features of These T2 Copper Flat Bar Pieces 🔶 T2-Grade Solid Copper Commercially pure copper with approximately 99.9% Cu content, delivering outstanding electrical conductivity (typically ≥57 MS/m) and thermal conductivity for demanding applications. 📐 Wide Size Range Thickness from 3mm to 15mm, width from 8mm to 100mm, and length in 100mm or 500mm — choose the exact cross-section your project needs without over-buying material. ✂️ Machinable & Solderable Cuts cleanly with standard metal saws, drills without burring, and accepts solder and brazing alloys readily — ideal for custom bus bars, terminals, and heat spreaders. 🛡️ Natural Corrosion Resistance Copper forms a stable oxide patina that slows further corrosion in most indoor and sheltered outdoor environments, reducing maintenance needs over the product's service life. 📦 Flexible Packing Quantities Available in packs of 1, 2, 3, or 4 pieces depending on the size selected — order exactly what you need for prototyping or small-batch production runs. 🔧 Square-Edge Flat Profile Consistent rectangular cross-section with square edges and a smooth mill finish — ready for immediate use as shim stock, spacers, grounding straps, or decorative inlay strips. 📐 Technical Specifications — T2 Copper Flat Bar Material T2 Copper (commercially pure, ≥99.9% Cu) Item Type Flat Bar / Flat Stock Thickness Range 3mm – 15mm (0.12 in – 0.59 in) Width Range 8mm – 100mm (0.31 in – 3.94 in) Length Options 100mm (3.94 in) / 500mm (19.69 in) Surface Finish Mill finish, smooth flat surface Edge Profile Square edges, consistent cross-section Electrical Conductivity Typically ≥57 MS/m (IACS ≥98%) Thermal Conductivity Typically ~390 W/(m·K) Packing Quantity See variant options Weight per Piece See variant options ❓ Frequently Asked Questions How do I choose the right thickness and width for my project? Start with your current-carrying or load-bearing requirement. For electrical bus bars, a wider and thicker bar reduces resistance and heat buildup — a 5mm × 30mm cross-section handles significantly more current than a 3mm × 10mm bar. For shims and spacers, match the thickness to your gap tolerance. Use the variant selector above to compare available Thickness × Width × Length combinations. How strong is T2 copper flat bar compared to brass or aluminum? T2 copper is softer than brass and harder than most aluminum alloys in terms of machinability, but its tensile strength (typically 200–250 MPa) is lower than structural steel. It is not intended for high-load structural applications. Its strength is well-suited for bus bars, terminals, heat spreaders, and decorative applications where electrical or thermal performance matters more than mechanical load capacity. Will copper corrode or tarnish over time? Copper naturally develops a surface oxide layer (tarnish) that appears as a darkening or eventual green patina. This patina actually slows further corrosion and is stable in most indoor environments. For applications requiring a bright finish, apply a clear lacquer or anti-tarnish coating. Copper is not recommended for direct exposure to ammonia, chlorine, or highly acidic environments without protection. Is this copper compatible with soldering and brazing? Yes. T2 copper accepts standard tin-lead and lead-free solder alloys readily, and is fully compatible with silver brazing and copper brazing processes. Clean the surface with flux before soldering to remove any oxide layer for a reliable joint. It is widely used in electrical terminal fabrication and plumbing fittings for this reason. Can I use this flat bar for grounding straps or bonding conductors? Yes. T2 copper flat bar is an excellent choice for grounding straps, bonding conductors, and earthing connections due to its high electrical conductivity. Select a width and thickness appropriate for the fault current rating of your installation. Always follow local electrical codes and standards when using copper conductors in electrical systems. What tools do I need to cut or drill this copper bar? Copper cuts cleanly with a standard hacksaw, angle grinder with a metal cutting disc, or a band saw. For drilling, use standard HSS (high-speed steel) drill bits at moderate speed with cutting fluid to prevent work-hardening and extend bit life. Deburr cut edges with a file or deburring tool. Copper does not require carbide tooling for most DIY applications. How do I decide between the 100mm and 500mm length options? The 100mm length is ideal for short bus bar segments, shims, spacers, and small decorative inlays where minimal waste is important. The 500mm length offers better value per unit length for longer runs such as grounding straps, heat spreader plates, or projects requiring multiple cuts from a single piece. Check the packing quantity for each variant — some sizes ship in multi-piece packs at the 100mm length. 🛒 Select your Thickness × Width × Length above, then add to cart. { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "How do I choose the right thickness and width for my project?", "acceptedAnswer": { "@type": "Answer", "text": "Start with your current-carrying or load-bearing requirement.
