T2 Pure Copper Round Bar — 250mm Solid Copper Rod
Whether you're working on electrical projects, metal fabrication, DIY crafts, or industrial applications, this T2 pure copper round bar delivers outstanding conductivity, a smooth metallic finish, and reliable dimensional accuracy. Available in diameters from 3mm to 10mm, each rod measures 250mm in length — ready to cut, shape, and put to work.
Key Features
- High-Purity T2 Copper: Features a fine-grain structure, ultra-low oxygen content, and zero porosity or trachoma. Electrical and thermal conductivity is second only to silver, making it ideal for conductive and heat-transfer applications.
- Available Diameters: 3mm / 4mm / 5mm / 6mm / 7mm / 8mm / 9mm / 10mm — choose the size that suits your project.
- Standard Length: 250mm per rod, with a manual measurement tolerance of ±0.1–0.3mm.
- Smooth, Lustrous Surface: The rod surface is polished smooth and full of natural metallic luster for a professional finish right out of the box.
- Highly Versatile: Suitable for electrical wiring components, thermal conductivity equipment, cables, wires, communication hardware, electronics, machinery, and home DIY décor projects.
- Easy to Work With: Easily cut, drilled, bent, welded, or shaped using standard metal-working tools — perfect for hobbyists and professionals alike.

Care & Maintenance Tips
Copper surfaces may develop a natural oxide layer over time — this is normal and does not affect the rod's conductivity or structural integrity. To restore the original bright copper finish, simply buff lightly with fine-grit sandpaper.

Frequently Asked Questions
Q: What is T2 copper and why is it preferred for electrical and thermal applications?
A: T2 copper is a grade of high-purity copper known for its extremely low oxygen content, fine grain structure, and near-zero porosity. These properties give it excellent electrical conductivity and thermal conductivity — surpassed only by silver — making T2 copper round bars a top choice for wiring components, heat-transfer equipment, and precision metalwork.
Q: Can I cut or shape this copper round bar at home?
A: Yes! This solid copper bar is soft enough to be cut with a hacksaw or pipe cutter, drilled, bent, and shaped using standard DIY or workshop tools. It's equally suitable for professional metal fabrication as it is for home craft and décor projects.
Q: Will the copper rod rust or corrode over time?
A: Copper does not rust, but its surface may gradually form a natural oxide layer (patina). This does not affect the rod's performance or conductivity. If you prefer a bright finish, lightly polish the surface with fine sandpaper to restore the original metallic luster.
Q: What diameter should I choose for my project?
A: The best diameter depends on your specific application. Smaller diameters (3–5mm) are ideal for fine electrical work, craft projects, and jewelry-making, while larger diameters (6–10mm) are better suited for structural, mechanical, or heavy-duty thermal conductivity applications.
