Important Notes

• Due to manual measurement, please allow a dimensional tolerance of ±0.1–0.3 mm.
• Copper surfaces may develop a natural oxidation patina over time — this does not affect performance. Simply polish with fine-grit sandpaper to restore the original shine.
• Product color may appear slightly different on screen due to monitor display variations.

Frequently Asked Questions

Q: What grade of copper is this rod made from, and why does it matter?

A: This rod is made from T2 pure copper, one of the highest-purity commercial copper grades. It features a fine grain structure, extremely low oxygen content, and virtually no porosity — making it ideal for electrical conductivity, thermal transfer, and precision metalworking projects where material quality is critical.

Q: Can I cut or shape this copper round bar at home?

A: Yes! T2 copper is highly workable and can be cut with a standard hacksaw or pipe cutter, drilled, bent, soldered, or welded with common workshop tools. It's a popular choice for DIY projects, electronics fabrication, and custom metal décor.

Q: How do I keep the copper rod looking bright and shiny?

A: Copper naturally develops an oxidation layer (patina) when exposed to air over time. This is purely cosmetic and does not affect the rod's conductivity or structural integrity. To restore its original bright finish, simply polish the surface with fine-grit sandpaper or a copper-safe metal polish.

Q: What diameter should I choose for my project?

A: The available diameters range from 2mm to 10mm. Smaller diameters (2–4mm) suit delicate electrical or craft work, mid-range (5–7mm) are great for general fabrication and wiring, and larger diameters (8–10mm) are better for structural, thermal, or heavy-duty electrical applications. Please allow for a manual measurement tolerance of ±0.1–0.3mm.
