Machinists, electricians, and hands-on builders who need a specific cross-section — not a compromise — turn to T2 pure copper flat bar plate. Whether you're fabricating bus bars, heat spreaders, grounding straps, or custom brackets, having the right thickness-to-width ratio from the start eliminates rework and material waste.\u003c\/p\u003e\n\u003cp\u003eEach piece is T2-grade pure copper flat bar, available in thickness × width combinations ranging from 10 mm × 20 mm up to 12 mm × 50 mm (approximately 0.39\" × 0.79\" to 0.47\" × 1.97\"), cut to a fixed 200 mm (≈ 7.87\") length. The flat-rolled surface provides consistent cross-section geometry and a smooth finish suitable for direct use or further machining.\u003c\/p\u003e\n\u003cp\u003eTypical applications include DIY electrical bus bar fabrication, RF shielding strips, thermal interface conductors between heat sources and sinks, custom grounding lugs, and decorative metalwork where copper's warm tone is part of the design.

For electrical bus bars, calculate the required cross-sectional area (mm²) based on your target ampacity — a common rule of thumb is 1 mm² per 1–2 A for copper at moderate temperatures. For structural or thermal applications, match the width to your mounting footprint and the thickness to your rigidity or heat-spreading needs.

These values are sufficient for bus bar clamping, terminal crimping, and light structural brackets, but T2 copper is not intended as a structural load-bearing material in high-stress applications — for those, consider copper alloys such as C110 or brass.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill these copper bars corrode or tarnish over time?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eCopper naturally forms a thin oxide layer (tarnish) when exposed to air and humidity, which actually slows further corrosion. In dry indoor environments, the surface will darken to a warm brown over months. In humid or outdoor environments, a green patina (verdigris) may develop over years. For applications requiring a bright finish, apply a clear lacquer or anti-tarnish coating. For electrical connections, clean contact surfaces with fine abrasive or flux before soldering or crimping to ensure low-resistance joints.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bars compatible with standard soldering and brazing processes?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. T2 copper is one of the most solderable and brazeable metals available. For soft soldering, use a rosin-core or water-soluble flux with standard 60\/40 or lead-free solder. For silver brazing, use a silver-bearing brazing alloy (e.g., 45% silver) with an appropriate flux at temperatures of 600–800 °C. Ensure the surface is clean and free of oxide before joining. The flat geometry makes fixturing straightforward for both bench and torch work.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I cut or drill these bars with standard workshop tools?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. T2 copper machines well with standard HSS drill bits, carbide end mills, and hacksaw blades. Use a slow feed rate and cutting fluid (or light oil) to prevent work-hardening and tool wear. For drilling, a sharp bit and moderate speed (300–600 RPM for 6 mm holes) will produce clean results. Cold-bending is possible in the 10–12 mm thickness range using a bench vise and bending bar, though tight radii may require annealing (heating to ~400 °C and quenching) to restore ductility.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhich size should I choose for a DIY electrical grounding strap or bus bar?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eFor a typical residential or light commercial grounding strap carrying up to 100 A, a 10 mm × 20 mm cross-section (200 mm²) provides ample conductivity with a safety margin. For higher-current bus bars (200–400 A), consider the 10 mm × 50 mm or 10 mm × 80 mm options to increase cross-sectional area. Always verify your local electrical code requirements for minimum conductor sizing before finalizing your selection.
